OFF not working on Hero/Boss monsters

I am not too sure if this is actually a bug, or with the recent changes when you fast-leveling with OFF you can’t kill Hero/Boss monsters - especially Boss units(ones with purple names) - they just don’t take DoT.

For early leveling( let’s say I am trying to level 50, so I can switch to Shadow Strike SpellBreaker).

Can you guys confirm if this indeed is a bug, or can you please provide an alternative to fast early-leveling.

Cheers,

Dmitry

Bosses always have and heros almost always have 100% freeze resist.

Am not talking 'bout the freeze.

I am talking about the Cold/Frostburn DoT(damage over time) they should be taking when they get hit with the Flash Freeze.

It says right on the skill tooltip that freeze resist will reduce the duration. If you can’t freeze something it will not take damage.

This. If they are immune to freeze, the damage will not trigger either. Which makes OFF worthless for anything other than CC for trash mobs.

I wish it would work against all trash mobs, though.

It does so long as they aren’t cold based like Cold Ones or the new cold Aetherials. Enemies with high cold resist like the yetis aren’t affected by OFF as much as your run of the mill skeleton.

Cold resist and Freeze resist are different values.
It’s Freeze resist reduces OFF duration. Even if you reduce enemy’s cold resist by 100+, it still retains his freeze resist. You should use items that reduce freeze resist, for example, Shard of Asterkarn.

In Ugdenbog those large slow guys are (as far as I can tell) not cold based, but they are not affected at all. Some of the Flesh Hulks in Act 4 also do not seem to be affected by OFF (others are, though).

My guess is they have a high freeze resist and/or high cold resist. A lot of the larger enemies in the game have ridiculous resists.
