Predecessor Builds > Phase > Tyrant's Phase
High Magic Power/Mobility/Healing
This build has given me lots of success. The build transitions Phase into being a little closer to damage support than I've seen most Phase players go. Of course dont go in guns a' blazing. Adding prophecy helps so you aren't completely helpless when cut off from your team and might even help you win a 1v1. By the time you get windcaller you should have decent enough mana regen to use your Flare as a constant speed boost/heal for you and your carry. Having Astral Catalyst makes it so you can Ult during any fight in the late game. This build usually lets you and your carry alone take down a full health core (using your ult) before the enemy team even knows you're there. It's even better to have good communication with your carry.
