I'm no Ellay either, but I did notice a bit that might help

Fight 1: IMO~, you should have redropped your whole totem set outside to make sure that your Searing totems and Tremors are able to be used to full effect. Also, in this arena I've found that it's easier to wait *just* outside so that they have to almost completely abandon the tomb in the middle in order to do anything to me. This way it's much much harder for them to LoS me.

Fight 2: I noticed that throughout all the fights you generally don't re-do Bloodlust Bad bad bad Boylston! Also, you probably should've redropped your Grounding totems there. In my fights they are always on cooldown.

Fight 3: GG.

Fight 4: Bloodlust!

Fight 5: Bloodlust!
