Usage
Warriors do little damage when you are buffed with Mist Form. This is because warriors mainly rely on attacks to do damage. As an Elementalist, you can still cast spells while buffed with Mist Form as attacking Warriors make futile attempts to hurt you, giving you a temporary advantage.

Combine with the Ranger skill Serpent's Quickness and an enchantment-lengthening weapon upgrade, to become virtually invulnerable to damage. See the article Invincimentalist. Using Arcane Echo with mist form is a good combination due to long lengths of invincibility that come out of it.

However, although using Mist Form prevents one from taking damage from attacks, any possible conditions delivered by those attacks will still come through, such as Poison from Poison Arrow, or Deep Wound from Dismember.
