Statistics are based on data shared on LaQoos, and may differ from the actual game.
When any friendly unit in the squad attacks and hits an enemy, all squad member’s ATK increases by 2.5%/2.8%/3.2%/2.6%/4% for 8s, stacking up to 4 times. The duration of each stack is calculated separately, and each friendly unit can provide 1 stack of the buff. Passive effects of the same name do not stack.
