Not sure, will have to keep an eye out for it next time.
I think it'd be good at least do it once to cripple his palm attacks.
@Neith
Haven't tried as melee yet. Quite frankly, I'm afraid to.
I think there's a higher chance of falling off the platform in lag, too.
If I had to guess, I'd say maybe Speed Rain?
Are you using lock on? That may help reduce the chance of falling off.
@Ce'Nedra
Good suggestion, thanks.
