Water 9 bless

[Gregstrom]

Or...

The Quickness effect from the spell gives +3 att/def and +100% AP.

Quickness from a W9 bless gives +50% AP (effectively, an extra set of attacks every other round) and does not give a +3 to att or def. However, you'll have at least +4 def due to your W bless.

If you cast Quickness at a unit with a W9 bless applied to it, you get the extra +3 att/def and your AP boost becomes +100% rather than +50%.
