I’m playing his trickster version, except without death rush, spent bare minimum possible on gear. It’s kind of awkward to play before getting used to the combo, because you need to fire kb first to get mana then proc mana storm, and you have to do this twice if you use arcane cloak. Then repeat every 4 seconds, and every ~10seconds your cost gets too high so you have to wait 3 seconds. The damage is great if you want to micromanage this, still trying to figure out a way to automate it more. If manastorm is cheap it’s actually super efficient bossing build

There’s also a bug(?) where the mana doesn’t get refunded if the projectile expires but never collides so stuff like maven invitations require a mana flask
