Why is the Hell's Precipice mission so much easier with Winter?

After several failures on the Hell's Precipice mission (the final mission), I re-specced my ranger to Wilderness Survival, and kept the Winter spirit up at all times. Though nobody in the party was wearing cold-resistant armor, it really seemed like everyone took much less damage, and the mission as a whole was pretty easy (even with Monk henchmen).

Winter is supposed just to convert all elemental damage to cold damage, but not mitigate it in any way. At least that's what I always thought. Maybe someone can explain its effect in Hell's Precipice?

Most all of the enemies in that mission, the Burning Titans especially, are weak against cold damage. When a ranger cast Winter and I hit a Titan with Lightning Orb I did 199 damage.

Every single monster in Hells Preciple is resistant to Fire Damage but weak against Cold Damage. By using Winter you turn all elemental damage to Cold, therefore any elemental damage you deal will deal extra to enemies, thus making them die faster - so you take less damage. There will have been no effect the other way, you will still have been taken just as much damage back from them, just maybe you had learnt the mission, or just had a lucky draw? It's not THAT tough a mission providing everyone takes their time, hell I did 3/4 of it purely with henchmen.

the faster things die, the less damage you take

yup i was using crystal wave and earthquake+aftershock and enfeeble+stoning and im telling you when winter was on i was killing these things solo

bring along a Ranger with winter and an ele with water, Hell's Precipice mission will be no problem.

And when you get to the last mission, hope the Ranger gets a chance to capture Greater Conflagration. :-)
