Fireball + Clemency + Guidance = Shield
Core + Frost + Flow = Infinite enemy stun + Infinite HP
Star + Momentum = light damage (for Frost to work).
Shadow + Quicksilver + Virtue = Mobility (Predation is for late game scaling).
*This build was inspired by and is an adeptation of the (Infinite HP + Boss Stun) build, which I did not create. I will provide a link to the original creators build in order to credit him.
