We 3D&D now!
You work that out, I'll stay quiet on trigonometry before I say anything stupid.
Let's take a step back and analyze the situation. I agree with Yulya that splitting up and going after them is deadly. Our strength is unity.
.)Nixie and Olga attack the wolves.
.)If they down them, Cat and me will go after the female bandit and flank her.
.)Yulya casts Toll the Dead Holocaust on the beastmaster if she can fly somewhere to see him.
Ideally we down everyone but the 2 male bandits.
If a wolf survives, Cat has to deal with him. Then she should go into the tree to avoid attacks
I will move out and shoot another poisoned arrow at the beastmaster before retreating into the tree.
