Buffs and Debuffs

Stacking of Buffs
Rule 1: Buffs of equal types do NOT stack

Rule 2: Buffs on the same attribute/roll/statistic do stack if their types are different

Rule 3: Buffs without a type (e.g. "+1 to Attack", instead of "+1 Discipline Bonus on Attack") do stack with eachother if coming from a different source (meaning you can buff the same attribute with 2 different spells/abilities which give a typeless bonus. These buffs will stack, but casting the same spell during the duration of the previous cast will only refresh the duration, NOT stack with the buff. Even if 2 different casters cast the same spell, the source (the Spell) remains the same, thus NOT stacking.

Rule 4: Always apply the highest Buff available

Rule 5: Casting the same Buff on a person if the source is the same does not stack (see Rule 3), however the duration does get overwritten if the remaining duration of the first instance is not longer than the duration of the fresh buff.

Stacking of Debuffs
Rule 1: Debuffs of equal types do NOT stack

Rule 2: Debuffs on the same attribute/roll/statistic do stack if their types are different

Rule 3: Debuffs without a type will stack if coming from a different source (see Stacking of Buffs Rule 3)

Rule 4: Always apply the highest Debuff available

Rule 5: Casting the same Debuff on a person if the source is the same does not stack (see rule 3), however the duration does get overwritten if the remaining duration of the first instance is not longer than the duratino of the fresh buff.
