Tags & Traits
Monster Tags
Creatures come in a variety of types, and might have more than one type. Monster tags do not frequently come into play, but are occasionally relevant for talents, spells, abilities, and the like. For example, the Cultist can occasionally summon a creature with the Occult tag. Creature types include mundane and planar groupings.
Mundane. Beast, Humanoid, Monstrosity, Plant
Planar. Avadri, Celestial, Eldritch, Elemental, Fae, Fiend
Some creatures might also have modifying tags or magic tags.
Magic. Arcane, Divine, Occult, Primal, Psionic
Modifying. Abominable, Constructed, Giant, Swarm, Shapechanger, and Undead
Monster Traits
Creature traits are shorthand for abilities that many creatures have in common. Creature traits that you might encounter in this document are listed below.
Ethereal
A creature with this trait can pass through walls and other barriers and surfaces freely.
Immovable
A creature with this trait cannot be teleported or moved against its will.
Immutable
A creature with this trait cannot have its physical form changed, such as with the Cloven Step spell.
Invisible
A creature with this trait is Unseen.
Iron Will
A creature with this trait cannot gain the Frightened or Shaken conditions.
Mythic
Mythic monsters are incredibly challenging to fight. A Mythic monster has the Iron Will and Steel Mind traits. A Mythic monster is also more difficult to kill: if it gains the Helpless condition, it is not reduced to 0 HP when it takes damage. Instead, all damage that it takes is considered critical.
Finally, Mythic monsters do not roll Initiative, but instead act after every 2 characters in Initiative order, making them much more capable of devastating a battlefield.
Regen X
At the start of each of the creature’s turns, the creature regains HP equal to its Regen number.
Steel Mind
A creature with this trait cannot gain the Charmed or Enthralled conditions
Unerring Mind
A creature with this trait cannot be tricked by illusions, disguise magic or magical effects, and sees the true form of any shapechanger or polymorphed creature.
Vigilant
A creature with this trait does not suffer any penalties to its AWR while Unconscious.
Recharge Abilities
Some monsters have abilities that they regain on a recharge or after a set amount of time. If an ability is followed by (Recharge X), that means that after you use the ability, roll 1d6 at the start of each of the creature’s turns until you roll equal to or greater than the Recharge number. Once you do, you regain the ability and can use it on that turn.
Some abilities such as the innate ability to cast specific Spells might specify 1/Day, 1/Recoup, or something similar. Monsters regain these abilities after the specified time has passed.
Monster Senses
Blindsight
A creature with Blindsight can “see” in some way out to a specified range without needing physical eyes, but is completely blind beyond this point.
Darkvision
A creature with Darkvision can see normally out to a specified range.
Low-Light Vision
A creature with Low-Light Vision does not suffer TD when making rolls that rely on sight within the specified range.
Tremorsense
A creature with Tremorsense can detect the footfalls of creatures out to a specified range, even if the creatures are Unseen. It cannot detect flying creatures or objects that are not touching the ground in this way
Truesight
A creature with Truesight can see a creature’s true form if it has magically disguised itself or changed its form. It also ignores the Unseen condition provided that the creature is not gaining Unseen from Total Cover or Darkness (unless the creature also has Darkvision).
Monster Speed
Some monsters have multiple kinds of speed. If a creature has multiple kinds of speed, it cannot use the sum of all of these types of movement; rather, each time it uses an action to move, it chooses which type of movement it uses.
Hover
If a creature has a hover speed, then they hover above the ground when they move. This allows them to ignore Difficult and Hazardous terrain, but it cannot elevate itself more than 5ft off the ground unless it also has a fly speed.
Jump
While moving, a creature may need to jump. A creature cannot jump farther than it can move.
A creature’s default vertical jump distance is 3ft + a number of ft equal to its STR.
A creature’s default horizontal jump distance is double its vertical jump distance.
Moving Through Creatures
A creature may move through an allied creature’s space, but this counts as Difficult Terrain. A creature may not end its turn in an allied creature’s space.
A creature may not move through a hostile creature’s space unless that creature is Paralyzed, Restrained, or Unconscious. In that case, moving through a hostile creature’s space counts as difficult terrain.
Creature Actions
Monsters don’t use AP like adventurers do; instead, they use creature actions. A monster’s stat block will explain how many creature actions they can take on their turn. High-power monsters may have several options, such as taking five normal actions or two or three much stronger actions.
Furthermore, if a creature has one or more Reaction abilities, then the creature can take one reaction per round unless otherwise noted. Some monster reactions (like the Wolf’s Growl ability) require them to take actions on their turn to prepare reactions.
Spellcasters
Some creatures can cast magical abilities like spells and prayers. When casting magic, refer to the creature’s actions instead of the magic ability’s APC when determining how long the ability takes to cast. This means that many magical abilities can be used slightly more quickly by creatures than by adventurers.
The exception is Conjuring. When a creature casts a magical ability with the Conjuring tag, they must continue to conjure that magic for the appropriate number of rounds as normal. For example, if a Mage uses its spellcasting action to cast a Fireball (which has Conjuring 1), the fireball triggers immediately at the start of the Mage’s next turn.
Innate Magic
Some monsters possess the ability to cast magic innately. This means that while they still must observe any Conjuring restrictions, they do not need to track SP when casting their magic.
Some spells have a set number of times that they can be cast innately. Track each spell separately, so if a creature has “(3/Rest) Circle of Haste, Fireball” it means that it can cast each of those spells innately three times, regaining all expended uses when it Takes a Rest.
When a creature innately casts a ritual or invocation, it does not need any material components to do so.
