quickness attack bonus?

I think that both add to a unit's AP/turn - bless adds 50% of base AP and the spell adds +100%.

So a unit with 10 AP base would have 25 AP with both effects active. That means 2 or 3 attack actions a turn, alternating (and less if the unit has to move between attacks).

I've done an experiment.

I gave a sacred unit boots of quickness, W9 bless, and cast quickness on them. Their AP was only doubled at maximum, never tripled or quadrupled. I've also had a group of blessed and quickened white ones (typically only one attack) engage an enemy, and I never observed any of them make more than two attack animations.

From this, I conclude that the extra actions are not additive; and that a 100% increase in _both_ AP and number of attacks is the maximum increase.

However, attack and defense were increased by +3 and +7, respectively. So attack and defense increase does stack.
