Ok thanks! Still not sure if I am suppose to lure the acidic spiders on me, on Arroxor or leave them be? Is there anything I can do to make Phase 4 a bit easier? She totally spazz's out on me in there.... :-/
Lure the spiders onto Araxxor near the end of phase 3. Doing this makes him a lot less accurate. After the fix I was able to just soul split Araxxi instead of trying to prayer switch which always kept messing me up. Just wear your best range gear, turn on protect from range for a second in the beginning to make araxxi mage, then soul split the rest of the way through.
