The Sear'd Ground created by the Burn Shell's "High Charge" Effect deals 0 Damage despite the description says it should deal half the damage dealt when activated to all enemies within the tiles.

EDIT:

Rather, it seems the Sear Tiles only inflict the damage towards the enemy that was hit by the Shell when proc'd, instead of any enemy who walks on the tiles.

Needs more testing/clarification.
