Seliad activates regeneration if possible, and moves as close as possible to the statue. If possible, she attacks (but I bet she can't).
Tria – fires a projectile at the warrior.
Ayaino –
If the paralysis from the projectile works, Locken should use cleanse.
If not... If the projectile doesn't hit, Locken should try to use shackles. If the projectile hits, but paralysis doesn't work, then there might be immunity to paralysis (there are no will saves against the projectile). Then Locken should use cleanse.
Castor – stays put.
Dillion – attacks.
