Sundowner Titan

Sundowner is an inexpensive shield-centric endgame build that uses the active block mechanic to delete monsters from the screen with Magma Barrier's retaliatory hit and the build's on-kill aoe explosions. Very good for breach, and hard on your framerate. Capable of 1 shotting pinnacle bosses.

Shield Charge around the map, and use Resonating Shield to perfect block a monster hit to proc your Magma Barrier. Infernal Cry can be used to give an extra layer of aoe detonate on death and extending the kill zone/lethality for Magma Barrier.

For bossing, use Shield Charge to apply your ignite and fire exposure, then Infernal Cry to boost the Hammer of the Gods hit.

Let me know what you think, open to any optimization suggestions.
