(New) Enemies permanently take 5% increased Damage for each second they've ever been Frozen by you, up to a maximum 50%
If two players each take the ''Enemies permanently take 5% increased Damage for each second they've ever been Frozen by you, up to a maximum of 50%'' Cold Mastery, would the freeze increasing damage taken stack up to 100% (50% from each player) if they can manage to freeze the boss that long?
No, the maximum increased damage taken any given target can have from this effect is 50%. But if a monster is frozen by two players, that maximum will be reached sooner.
