Stagger

Stagger is a debuff that appears next to your defense in your prompt. It
represents a general lack of balance or short term fatigue in combat. All
attacks add some stagger when they strike you, but the amount depends on the
conditions of the attack. Most supernaturals will take bonus stagger from
certain types of weapons to which they have a weakness.

Stagger decreases your damage and movement speed, and is particularly
effective at diminishing the effect of in combat magical abilities. It goes
down every round and goes down more the less you’ve moved that round as well
as the higher your stamina is.

An attack needs to do at least 10 damage to inflict stagger. Forest monsters
inflict 5 stagger every attack regardless of damage.
