Units with this trait can the listed value at most in Damage, when hit by the Enchanted Salt attack.

For those who don't know, the actual Damage you take from Salt is capped after its Damage Roll, and independently from its attack Damage (which is 1). For units without Salt Vulnerability, the cap is zero. Getting hit by Salt can still break your Glamour, though, if the Damage-versus-Protection DRN is above zero before the cap is applied.

Salt can also Stun Vulnerable and non-Vulnerable targets in this manner, with the same chances as Shock Damage.
