When I found out that the tentacles guardbroke and procced sharp claws, I actually wanted to try something like this. It seems you beat me to it though lol
before i added the necrotic, i were with a good sustain, but after i add this, the healing just sucks. i have 3 necrotic, cz i noticed that i stopped adding necrotics necrotic is the last thing to complete the build tho edit: i just saw your newest video, im so sad right now.
