EX Hellblade advice?

I'm trying to solo that fker because I'm a masochist.

My weapon of choice was adept GS but after enduring through a 30 minute hunt and getting just 2 topples (yes I'm landing most of my upswings on the head with 100% affinity and crit boost with avydia GS) I'm starting to think GS adept's upswing is pretty underwhelming.

My new weapon of choice is longsword with the same meta set every speedrunner goes for.

I need as much advice as I can get because that son of a lizard chews my HP through the valor dodge and... Yeah, EX Hellblade what a fight.

Come on! Help a brother get his drip!!
