A sacrifice you should make. Tanks are only strong because they straight-up ignore CEL, AND, by making CEL matter for Duelists, you're giving the stat some importance. So win-win. Your words telling this, Shujin. Plus, this can't even be a hassle for tank ghosts, they gain CEL when their HP is low anyway. /shrug

The most acceptable way is to use the OP's suggestion, so Eviter becomes something like this:

Rank 1: 5 + Scaled CEL% chance.
Rank 2: 10 + Scaled CEL% chance.
Rank 3: 15 + Scaled CEL% chance.
Rank 4: 20 + Scaled CEL% chance.
Rank 5: 25 + Scaled CEL% chance.

Success reduces the damage by 10 + (WPN Durability)%, and WPN Durability by 1.
