Damages that CANNOT be reduced by Cushioned Padding
An interesting piece of information: Most damage related to "maximum health" cannot be reduced by cushioned padding, or armor.
For example: Orisa's burn, reaper's burn, and TTT.
However, if these damages are from Powers, they are classified as ability damage. They can be reduced by the "reduce 10% ability damage" item and can trigger any "ability damage" items such as cyber venom.
[For instance, TTT and brig's rally burn are items, so they are not ability damage. They cannot trigger cyber venom or be reduced]
Another interesting info: Rein's shieldbash power is not ability damage, it is melee damage. It's interaction with dark gloomlet? Only triggers 5% life-restore (messy as ever).
