Abilities tagged with (Melee), (Projectile) or (Area) all are considered weapons and deal (type+escalation+modifiers) damage of the selected type. All weapons inflict the Bleeding condition and critically hit (ignoring defenses) on a trigger die result of 12.

Some ability trees have associated weaknesses listed below them. Weaknesses are optional; you don't need to take the weakness to take advantage of the tree. If a creature has a weakness, they may select one ability per every three levels they have from the associated tree to equip in their loadout for free. The weakness and the selected abilities are never unequipped or transferable. Once/if a creature hits level 30 (and thus has all 10 abilities from their weakness's associated tree) they stop accruing any additional benefits from the weakness when leveling up. Creatures that are level 1 or 2 still gain one free ability from a weakness, but don't gain a second until level 6 as normal.

Trees accessed through a weakness still count as one of your ten known trees.
