Clever way to make a beast turret. Beasts usually have good mobility, homing projectiles for a normally immobile object is a pretty good advantage even if it loses some damage. Cue Nick Cage references.
Totem reminds me of something from the old Transformers movie in 1986 with Unicron, meaning it has to be gudd. Would its defenses change with the face or would it be neutral to everything except whatever face is active to make normal damage weapons more useful?
Beast-themed turrets?
Indecisive damage-dealing monster types?

The names for the turrets could do with some tweaking; they seem a little... uninspired, somehow.
Hornet Hive? Buzz Burner? I don't know, I'm just trying to come up with something a little more subtle.
The rest of the idea is awesome, though. I like the idea of another enemy that can provide buffs, too.
