Fast casting vs other mages.. better to be second?

[Berengar]

@Cuchulainshound

But what does that mean in this context?

Which context are you pointing at, without naming it?

@Cuchulainshound

It does not unequivocally state whether it resolves before the casting of a(n attack) spell, or just the effect of that spell once cast.

Wouldn't that depend on the Fast-Cast spell, in particular its Target?

I hope this shall not become a discussion, with scarce text base and lots of opinion, about what Fast-Cast spells can target.

Cheers
