Demon Slayer (XC1)

Demon Slayer is one of 's topple s in Xenoblade Chronicles. It is a strong attack, and if it kills its target, all other enemies in the battle are automatically d (unless they are flat-out immune).

Overview
Dunban must be careful to use Demon Slayer at just the right time; the attack being strong widens the margin for error a bit, but if it's mistimed (or his allies do something unexpected), its massive cooldown is still spent. When it does trigger however, the party gets their choice of which enemy to or potentially topple-lock, and it also acts as a "stop what you're doing" button to everything that gives the team a breather. It's not bad in chain attacks either, since it does high damage and its cooldown will not be spent, and a chain multiplier will make it easier to kill the foe (although some planning of previous attacks might be needed).

One strategy with Demon Slayer is to use it to kill a low-level enemy in order to topple a high-level enemy that's also in the fight. The special effect does not go through an accuracy or evasion check, and the now-toppled foe can no longer dodge, allowing the party to lay into an enemy that may otherwise be difficult to hit.
