The Dark Guild's Servant (star trial) is up next with Irene up for a light patting on the head.

Hmm interesting, our first Maid it seems. Maids, as is their role in life and society, strengthen their masters and give them various boosts. They also tokennize (spelling please) their masters as well making those three stars just a little bit easier. Not sure if I should mention 2AW since that's very far away.

All Maids specialize in a particular theme with Irene focusing on "outlaw" units. Base ability gives Bandits 7% extra max health and Rogues 20% extra skill duration. AW'ed ability adds Pirates and Thieves in the mix giving them 5% extra attack and -1 cost respectively; though honestly who fields Thieves anyway?
Irene also gets a good skill as well, with max skill doubling her attack and defense for 30 secounds. SAW decreases the boost to 90% for the same duration and makes her attacks ranged (200).

All in all Maids are probably the most solid support units in the game I think. They are both able to boost their fellows and hold their own in a pinch; definitely worth the effort of perfecting.
