Water blessing gives Defense as the low-level ability and Quickness (extra action every other turn) as level 9 ability. At level 9, Water gives +4 def, at 10, +5 def.

Quickness given via the spell or from an item (it's the same effect) gives +3 attack/+3 defense, and an extra action every turn.

Heroic Quickness gives an extra action every once in a while, starting from about 10% and increasing with time. I'm not sure if it gives attack or defense bonuses, but I don't think so.

I think the confusion comes from bless quickness just giving defense, while the spell also gives attack.
