What are the applications of Divine Protection and Guardian's Barrier?

Someone running fast can pick up 3-4 shards in RMHM when divine shield is on. 0 dmg taken.

I shielded the laser after pushback at 30% at once. It felt useful.

You can Divine Shield or Guardian's Barrier the "S mechanic" in RK9.

You cannot divine the first boss' bombs in RK9.

People can just chill and dps when Darkan goes up and you divine shield. It feels good as lancer. Must be same for other dps.

If you're a bad at dodging KN normal's big jump, go to your fellow lancer. He will divine shield you.

More to come as i play.

I think you resist CC stuff in divine shield too.

Divine shiled always gets me hit by debuffs but no damage is done to myself, is it specific debuffs that don't affect you?
