Riki is Angry

Riki is Angry is one of 's aura s in Xenoblade Chronicles. When activated, it gives Riki a counter spike, dealing damage back to the attacker based on how much damage Riki took. Unlike normal counter spikes, it remains active when Riki is toppled. However, it does not trigger against talent arts.

Overview
With such a huge cooldown for an aura, it's not remotely feasible to have Riki is Angry up most of the time. Thus, it's more of a reactionary move, for when Riki's grabbed the aggro and wants to make good use of it before it slips off him again (as Riki has no good way to keep hold of aggro like a tank does). Arguably, having this aura equipped means Riki wants to have lower defence, so he can deal more damage back to enemies.

Additional data
The damage done by the counter spike is equal to 2x, 4x, or 8x of the damage Riki takes (unless the attack was a talent art, in which case it is 0x). The exact probabilities of each multiplier are unknown, but manual testing suggests that is is close to this: Thus, the average multiplier is 2.5x.
