Hmm, haven't played FE4 I believe. But even so, doesn't Astra allow the swordmaster to strike five times on the target, which is like a critical hit on steroids anyways so it's usually a killing blow.

Before FE9,Astra dealt 5 full damage strikes,but,on that game,it deals half damage each strike.

But it's still really powerful skills,and can make your life much much easier,although,at long term,Luna is more powerful(negate defense)

True.
