Special:
Components:	FocusFocus: A focus component is a prop of some sort. Unlike a material component, a focus is not consumed when the spell is cast and can be reused. This has no gameplay applications in DDO, as all characters are always considered to be carrying a focus component at all times and it does not require a inventory slot., MaterialMaterial: A material component is one or more physical substances or objects that are annihilated by the spell energies in the casting process. You must have the required items in your inventory. If you run out of the components, the game will not allow you to cast the spell and will instead inform you of what component is missing. The metamagic feat Eschew Materials and some enhancements in Draconic Incarnation can remove this restriction. , SomaticSomatic: A somatic component is a measured and precise movement of the hand. You cannot cast spells that require this component if you cannot move causing arcane spell failure resulting in a ruined spell. Spells without a somatic component may be used with disregard to Arcane Spell Failure chance. Note - that characters make the same arm gestures for most spells in DDO, so you can't tell which spells require this component by watching your character's animations., VerbalVerbal: A verbal component is a spoken incantation. You cannot cast spells that require this component if you cannot act or speak. Certain rare spells, such as Silence Creature, may temporarily disable spells that require verbal components.

Description

A billowing mass of misty vapors causes several effects:

• Slows movement (~-5%).
• Obscures sight, giving all creatures in the fog concealment (Attackers have 20% miss chance).
• Deals 2d6 acid damage every 2 seconds to targets within the cloud.
• Enemies within this cloud also suffer a -4 penalty to their armor class.

Notes:

The movement speed reduction is very small and almost un-noticable after recent nerfs. Perhaps -5% at best.

Also unlike many other persistent AOE, it has no initial tic, making this a rather poor spell for dealing damage. Acid Rain is far superior for this purpose.

Immunity notes:

Purple named are immune to most effects of this spell - only the damage and armor class penalty applies.

Red named are immune to only the slowing portion.

Also due to the way freedom of movement is programmed, in addition to preventing the slow, it also provides immunity to the miss chance from this spell for any monsters that cast/possess it.
