Combat Quick Reference for MCs

From MythCraft Online SRD
Jump to navigation Jump to search

This contains basic combat rules along with a list of maneuvers and conditions that might come up.


If you crit with a creature, you can easily just look at their average damage and add that to the size die that the attack does. For example, if a Veteran Soldier crits with a longsword that does 7 (1d8+3) damage, a crit would be 15 damage (the average, plus 8 for maximizing the critical damage die).

Combat Maneuvers

Ranged Attacks in Melee

If a creature makes a ranged attack or thrown attack with a weapon, spell, or any other effect and a hostile creature is within 5 ft of it, it suffers 1 TD for each hostile creature within 5 ft.

Basic Maneuvers

Maneuvers are actions that creatures can take in combat to gain an edge in certain circumstances. Any creature can use any Basic Maneuver.

  • Dodge (1 monster action). Gain +2 to your AR and Physical Defenses until the start of your next turn.
  • Drop Prone (0 creature actions). You gain the Prone Condition.
  • Grapple (1 monster action). You may attempt to Grapple a creature (see Conditions below). Make a STR or DEX attack roll against the target creature’s REF or FORT (their choice). If you hit, they are Grappled.
  • Shove (1 monster action). Make an attack against a creature, using your STR and targeting their FORT. If you hit, push the creature 5 ft in a direction of your choice. You cannot do this to a creature that is more than 1 Size larger than you.
  • Stand (1 monster action). You stand from being Prone. You cannot do this if your Speed is 0. A monster can do this in place of moving if it used its Move feature.
  • Trip (1 monster action). Make an attack against a creature, using your STR and targeting their REF. If you hit, the creature falls Prone.

Advanced Maneuvers

Some creatures have the ability to use advanced maneuvers. If an ability does not specifically give a creature access to an advanced maneuver, then that creature cannot use that maneuver.

  • Exploit (1 monster reaction). When a creature within your Melee weapon’s Reach does one of the following actions, you may make an attack against that creature immediately.
    • Moves out of your Melee weapon’s reach
    • Administers a potion (drinking it themselves or feeding it to another creature)
    • Makes a Ranged attack while within your Melee weapon’s reach
  • Disarm (2 creature actions). Make a STR attack against a creature’s REF or FORT (they choose). If you hit, choose an item that the creature is holding; they drop that item.

Knocking Unconscious

A creature that deals blunt damage can choose to deal nonlethal damage.

When a creature reduces you to 0 HP with nonlethal damage, you regain 1 HP and become Dazed. If you were already Dazed, you regain 1 HP and become Stunned. If you were already Stunned, you regain 1 HP and fall Unconscious.

When Dazed or Stunned in this way, you remove the condition when you are no longer Bloodied or when you have 15 or more HP (whichever is lower), or when you Catch your Breath.

If you want to knock an NPC unconscious, then use this system if the alternative would be the NPC gaining death points (some major villains may have this feature, at the discretion of the MC). If the NPC is assumed to die immediately, you can immediately knock it unconscious instead.

Combining Magical Effects

Spells and magical effects of exactly the same name cannot stack on a target. The newer effect always replaces the older effect.

Tactical Advantage and Disadvantage

When you have Tactical Advantage (TA), add +1 to d20 rolls you make to attack with a weapon. You can have multiple sources of TA, and they accumulate indefinitely. Similarly, when you have Tactical Disadvantage (TD), subtract -1 from d20 rolls that you make on any kind of attack (weapon, spell, maneuver, etc.). You might have several sources of TA and TD at once, so be sure to account for all sources!

You gain TA through clever implementation of Conditions, such as attacking a Prone target.

Conditions List

During combat, you might impose conditions on your enemies or have them imposed on you. Conditions are specific words referenced in monster abilities. These conditions are written specifically to adjudicate how monster actions work. The same conditions are worded to interact with an adventurer’s AP on the Conditions page.


When a monster has an Affinity with a type of damage, it takes 1⁄2 of that type of damage, and deals +3 additional damage whenever it deals that type of damage.


A creature suffers Bleeding at the beginning of each of their turns, taking the amount of physical damage specified. This might be a set number or a die roll, such as Bleeding (1d4). The effect is ended by receiving any amount of magical healing, Catching your Breath, or by receiving a successful Intelligence (Medicine*) check. The Difficulty of this check is the Bleeding damage + 10. Attempting this check costs 2 creature actions. The creature can make the check themselves or have an ally make the check on them, provided that the ally is within 5ft of them.


A creature cannot see or gain any benefits from any ability requiring sight. All creatures are Unseen.


A creature gains the Bloodied condition when it has equal to or less than 1⁄2 its maximum HP.


A creature is Frightened and Shaken. It must use all available movement to retreat from perceived danger.


A creature suffers Burning at the beginning of each of their turns, taking the amount of fire damage specified. This might be a set number or a die roll, such as Burning (1d4). The effect is ended by being doused in water or by rolling in dirt or mud by falling Prone and spending 2 monster actions.


A creature looks upon the creature that Charmed it as a friendly acquaintance. It will not intentionally harm the creature that Charmed it. When that creature targets your ANT, LOG, or WILL, they get TA. When that creature makes an INT or CHA check to interact with the charmed creature, they roll 2d20 and use the higher result. Unless stated otherwise, the creature knows it was charmed after this condition fades.


A monster can take one fewer actions than it normally would (minimum one action).


A creature is Concealed when Line of Sight is interrupted by fog, smoke, foliage, or other obscuring phenomena, but not sufficiently enough to remove Line of Sight altogether. While Concealed, a creature has TA on attacks provided that it can see its enemy, and attacks against it have TD.


If at least 1⁄2 of a creature’s body is protected by an object that would block physical damage, then it has Partial Cover. Its AR and physical defenses gain between +1 and +3 against ranged attacks, determined by the MC and the amount of cover the creature has. When a creature has Total Cover, it cannot be targeted by ranged attacks or any effect that requires Line of Sight to it.


The creature’s current number of creature actions is reduced to 2, unless it was already 2 or lower. It must take one fewer creature actions than normal on its turns while Dazed, and cannot take reactions.


A creature cannot hear and is immune to effects that require hearing. It automatically fails any roll that requires it to be able to hear. Casting magic that requires verbal input requires it to roll 2d20 and take the lower result.


All attacks against a Demoralized creature gain TA.


Typically, when a creature reaches 0 HP, it immediately dies or falls unconscious. The MC may decide that particularly important creatures or NPCs use the same Death Point and Unconsciousness system that heroes use.


A target that is Engaged provokes a free Reactive Attack when it leaves the reach of the creature that has Engaged it. If the attack hits, the creature takes damage as normal and its speed is reduced to 0 until the start of its next turn.


A creature is Charmed and loses its sense of self, following the instructions from the creature that Enthralled it even to the point of putting itself in danger. The Enthralled creature will not intentionally harm the creature that Enthralled it, and will not undertake actions that will obviously lead to its death. For example, an Enthralled creature may attack their ally, but would not fall on their own sword. When a creature that Enthralled another creature attacks its ANT, LOG, or WILL, or makes a check against it using INT or CHA, they roll 2d20 and use the higher roll.


If a creature suffers Fatigue, it immediately gains 1 Death Point and becomes Fatigued. While Fatigued, it does not remove Death Points when it Recoups or Takes a Rest. Instead, when it Takes a Rest, it removes the Fatigued condition if it eats and drinks the minimum amount needed to sustain it.


Flanking is achieved when two friendly targets threaten a border or corner opposite of one another. If a creature is larger than one square, or has a Reach of more than 5ft, it counts as Flanking if it threatens a space on the opposite border or corner from an enemy creature.

A creature is only considered to threaten a square if it is able to melee attack that square. A Prone creature can flank, for example, but an Unconscious one cannot.


A creature gains TA against a specific target. When it gains this Condition, it will specify which target it gains TA against.


A creature has TD while the source of fear is in sight, and cannot willingly move closer to the source of its fear.

Grappled and Grappling

If a Grappled creature is the same or a smaller size Category than the creature Grappling it, the Grappled creature’s Speed becomes 0ft and the Grappling creature’s speed is halved.

If the Grappled creature is 2 or more size categories smaller than the Grappling creature, the Grappling creature’s speed is unaffected.

If a Grappled creature is 1 or 2 size categories larger than the creature Grappling it, the Grappled creature’s speed is halved, and the Grappling Creature’s speed becomes 0ft.

If a Grappled creature is 3 or more size categories larger, the Grappled creature’s speed is unaffected, and the Grappling creature’s speed becomes 0.

On its turn, a Grappled creature can try to break out of a Grapple once per turn by spending 1 creature action to make an STR attack against the FORT, or DEX attack against the REF, of the creature that is Grappling it. On a success, the creature frees itself.

A creature who is Grappling can let go at any time without spending AP. Forced Movement does not end the Grappled Condition. If the Creature who is Grappling is subjected to Forced Movement, the Grappled is moved with it. If the Grappled creature is subjected to Forced Movement, the Grappling creature decides if the Grappled creature moves or not.


A creature cannot teleport or move to a different plane, nor can an external effect impose teleportation or plane shifting effects on it.


When a creature takes Melee damage, it loses all of its HP.


A creature is Helpless and it can take no creature actions or reactions while Paralyzed.


A creature is Frightened when it can see the subject of its phobia. This effect is permanent until removed.


A creature is Prone, Grappled, and gains an additional TD on attacks. Creatures making melee attacks against it gain TA, and creatures making Ranged attacks against it have TD.


A creature has TD on all attacks while prone, and cannot make attacks with two-handed weapons. Additionally, melee attacks against it have TA, and ranged attacks against it have TD.


A creature gains +2 to its AR and Physical Defenses while Protected.


A creature cannot be Demoralized, Frightened, or Shaken. If it is already suffering from one of these Conditions, the effects are suppressed while Rallied.


A creature is Grappled. When attacking a Restrained creature, roll 2d20 and use the higher roll. Unless otherwise stated, escaping the Restrained condition is the same as escaping the Grappled condition, but requires 2 creature actions.


A creature suffers a -2 penalty to all d20 rolls.


Whenever rolling a d20, roll 2d20 and take the lower result.


A creature cannot vocalize. It automatically fails any roll that requires the ability to speak or use verbal components.


A creature’s speed is halved.


A creature can take only 1⁄2 the creature actions that it normally would.


The creature’s current number of creature actions is reduced to 1, unless it was already 1 or lower. Its maximum number of creature actions cannot be raised above 1 while Stunned.


After Suffocating for a number of rounds equal to a creature’s END + 1, it gains a Death Point at the start of each of its turns.


You cannot use your AP to move.

Surprise (Complete)

Complete Surprise only occurs when a creature attacks an enemy under all of the following conditions:

  • The target does not perceive the attacker and is unaware of their presence.
  • The target is not in a heightened state of awareness or on alert. For example, an alarm being raised, or being actively in combat, even if it’s with a third party, disallows a full surprise round.

In this instance, the creature who begins combat is granted double their AP or number of creature actions and takes a single turn.

If the defender survives this attack, that creature and its allies are Partially Surprised and combat begins. If the creature that is attacked is reduced to 0 HP or knocked unconscious and the attacking creature is Unseen, the victim’s allies that are within 30ft make an AWR check against the attacker’s DEX. If the attacker wins all skill contests, it remains Unseen and combat does not begin. Otherwise, Initiative is rolled and Partial Surprise rules apply to all Surprised creatures.

Surprise (Partial)

If creatures are surprised, they don’t act on the first round of initiative and have TD on the second round. They cannot use reactive actions until after their first turn in which they can take action, and do not carry over AP until after their first turn in which they can take action.

Creatures that are not surprised have TA on the first two rounds of combat against creatures that were surprised.


A creature has TA when attacking the creature that Taunted it, and has TD attacking other creatures.


The creature must roll three dice and take the lowest result to perceive checks that rely on sound. They automatically fail checks that rely on vision. A creature can be shaken awake by another creature who expends 1 monster action as long as they have at least 1 HP. Taking any damage automatically ends this effect. An Unconscious creature is Helpless.


An unseen creature gains TA, and when it makes an attack, it rolls 2d20 and takes the higher result. It cannot be targeted by Line of Sight effects. Unseen Creatures are also considered Concealed. Unless the source of the Unseen condition states otherwise, the following would cause you to lose the Unseen condition:

  • You make an attack or cast a spell that deals damage
  • You are struck by a melee attack
  • A creature would occupy the space you are in as part of their movement
  • You are hit by an attack where the attacker indicated which square they thought you were in
  • You move into the clear line of sight of a creature, such as into bright light, out of concealment, or something similar

When trying to spot an Unseen creature, you can spend 1 monster action once on your turn to attack an Unseen target’s ANT with your AWR. If you win, you know what square it is occupying, but it remains Unseen. If it is more than 60 ft away from you, you automatically lose.

If you are the target of a ranged attack or effect from an Unseen creature, you know which direction the attack came from. If you are the target of a melee attack from an Unseen creature, you know which square you were attacked from.

When attacking an Unseen creature, indicate which square you are attacking, roll 2d20, and take the lower result. You know if the attack hits, but gain no information from missing.
