Drowned are one of my new favorite minions, and toys Kirai gets to play with. In a Kirai crew Kirai can heal them (they can wound themselves to get extra movement), she can swap them with other spirits and have them blow up in someones face.
They float and have gunfighter so they can keep vomiting while in melee. The best thing about them is their riptide spell and their Ca/Cb trigger Fluid in the Lungs. It needs a :crows.
For their weapon, Heave Bile, it has a damage of 1/1/3 It might not seem like much but if you get the trigger, the model you are attacking suffers a damage flip as normal, AND must beat a Df->12 duel or suffer an additional wound and slow.
Thier spell Riptide is amazing. You need at least a 9 to get it off. If the defender fails to resist, they suffer 2 Wds AND other models within 2 inches of the first target has to beat a Df->11 duel or also recieve 2 wounds. If you get the trigger, after the initial target suffers damage, they have to beat that Df->12 duel or receive slow and an additional Wd.
Thier (0) is pretty snazzy too. It is a Wp->Df duel. If you win, you get to push the defender 3 inches where ever you like.
To top it all off, when they die the produce a 4 inch of 2 Dg
Imagine all that, while having Kirai Sprinkled all over.
