Sacred 2:Damage over time: Ice
Combat Arts that Cause Damage Over Time: Ice
Damage Mitigation: Physical +X%: modifier reduces DoT duration (as well as total damage: for example, if incoming DoT was to inflict 250 damage for 5 seconds it would be decreased by "Damage Mitigation:x +65%" to two seconds - 250 damage dealt by the first pulse and 187 damage a second later, summing up to 437 damage which is 35% of initial 1250). Modifier can stack with similar other without diminishing returns, so immunity can be achieved.
Spell Resistance skill mastery reduces the duration (as well as total damage).
