Build Description
Auras at hint 2 need to touch the 6DU buff beam in order to cover down around hint 3. I can do this with 5.2k range. Higher range will let you can place them closer to the crystal so you may have to fiddle with the placement.
Only have tbooster out. 3* buff beams, activate TBoost around first 40 killed to sustain through ogre rush.
