wow Serious? Mini Bst Burn Makes easy work of this?
1 more thing, try to make sure they are competent bst. in this fight there should be no melee other than pets. hate control is the thing that makes it work. all cures and buffs need to be well away from haku. only 2 things that should really happen is bst charm million eyes. Fight then sic pets, wait till pet is on low on hp and switch out. if someone is feeling brave then they can cast dia 2(i do it when i go). after about 40 min and many pet swaps, you will have a new hat. i have done it w/ as few as 3, little more dangerous, heard it can be done w/ 2.
