Uses 2 hacks:

o Reduced spell distance due to lack of hitbox support/to small hitbox of boss_thadius. Full range would make offlike tactic unusable, and boss almost impossible to kill.

o Cross-use buffs 29659 and 29660, because they replace their parent aura, and I have no knowledge of aura slots/stacks/etc to fix it the right way (Perhaps the reviever could do that).
