Stacking: ATK Down | DEF Down

ATK is greatly boosted based on how low HP is.

Jammed is a unique ATK buff that stacks multiplicatively with all other ATK buffs such as ATK UpATK is boosted
, HypeATK is boosted
, etc.
Single target Jammed will stack with teamwide Jammed; two effects of the same stacking side will replace each other based on strength, regardless of source.
Regardless of its side, Jammed stacks additively with Enmity from Character Extended Mastery Perks and Over Mastery Bonuses.
