This build, others have taken it pretty far. its mostly just a concept though you can tweak it, get better ward values etc.
im pretty sure you could get a cleaver solution version to get insane ward.
The core idea is just really the node inside spriggan, which gives %inc phys damage, and %bleed chance per shield, this is double scaling per shield so you scale a ton of cast speed and just get tons of shields on the bear which then gets hit and retaliates spikes all over.
Going to high corruption is all about surviving, and this build is extremely beefy.
