I should read ASB moves more closely... Ah well. First of all, chant a Perish Song. There's no way he can avoid hearing it, it's way too loud. Then, squeeze him around a bit with Night Shade. Finish it with a Confuse Ray. However, if he somehow avoided the first Perish Song and he's not underground (if that's the case, well... he's only taking tons of damage^^), chant Perish Song again!
Perish Song - Night Shade - Confuse Ray
If Perish Song was avoided 1st action and he's not underground, cast Perish Song again instead of Confuse Ray.
