This build takes damage resistance to the extreme for 91.04% Damage Resistance
Here is how to do it:
Pop over-shield, get a kill with ruinous, pick up the orb and ball, throw glacier grenade, guard.
YOU ARE NOW INVINCIBLE (at least until the ball starts to kill you)
Dunk, repeat until the over-shield is almost fully depleted or everything is dead.
Manually deactivate depleted over-shield, get kill with ruinous, pick up ball.
Guard if you need health, dunk if you don't.
Repeat once the over-shield is ready again.
