I think when something was done with Walter's code it broke MacTusk and their attacks. Right now you can run into your triple Mac biome and aggro all of them. They will play the animation of their attack but not do any damage to you. Their hounds still bite, but their darts don't land. Please look into it, thanks!

3. Mac goes pew pew pew
4. Attacks don't land and don't break frozen (from hounds) and deal no damage
5. FREE DROPS!
