Decimation special attack which makes all attacks AOE. Pretty sure there’s nex, 4 minions, and a dummy underneath. Then they all use SGB spec at the same time and since nex is a 3x3 3 arrows land on each of the 6 targets. With 2 of each arrow hitting nex so 13 arrows at 15,000 damage each hit nex on the same tick and there’s 7 players so that’s up to 1.4m damage possible.
