Your dragonmark tingles as its energy blocks the most potent attacks of your adversaries.

Any critical hit or sneak attack made against you has a chance to be negated so that damage is instead rolled normally. The chance depends on the strength of your dragonmark.

Dragonmark	Normal Damage
Least	25%
Lesser	75%
Greater or Siberys	100%

The benefits of this spell do not stack with any other effect that grants a percentage chance to negate extra damage from a critical hit or sneak attack.

Dragonmark: Any true dragonmark.
