Hey it's TPB, this build is a ton of fun to play and is a great mapping character. I'll be league starting as this, and it has a full progression on my Maxroll article if you like to digest information, or need a bit more guidance on upgrades.

You level as Pconc occy until level 88-90 and swap when you have cast speed everywhere, a large phys, a chaos medium, crit medium, a mana reservation smallcluster, a despair on hit ring, a life gain on spell hit shaper ring, and shaper gloves rolled with faster casting. It sounds like a lot but half the gear is caster reforges, and the rest is alterations. If you need full crafting notes for everything checkout the article :)
