Test build

Spellbreaker for shield against abilities

Orb 2nd for its scaling magic power

Azure 3rd for midgame fights and another shield for ULT

Bracelet for health stacking and shield for ULT

Megacosm/ wraith (either or) depending on play style. Wraith for me personally for movement speed and additional damage for late game fights.

World Breaker you can get earlier for the stacks, but I prefer last for the big magic damage boost.
