Requirement(s) Undine
When the air is full of water, your elemental blood allows you to blend with your surroundings and become one with the precipitation. In areas of nonmagical fog, rain, snow, or similar conditions (such as the spray of a waterfall), you gain the effects of concealment, but with a miss chance of 10%. If the precipitation would already grant you concealment, the miss chances stack.

So, what's the difference between gaining the effects of concealment, and gaining the real deal?

As far as I'm aware, concealment grants you a miss chance and the ability to hide with stealth. The effects of concealment should be the same.

So would the benefit of this trait not prevent a (chained) rogue from sneak attacking you, but prevent a Heartseeker bow from ignoring the miss chance?

Does this sound right, or is there some similar ability that can provide an example?

Normally concealment is 20%. This is telling you "does everything concealment does only with 10%. Or 30 if it stacks", like being in a fog cloud spell or some such

It's changing the % but not anything else, so you know what it does.

non-magical only. Won't come up too often.

[Wonderstell]

Ah, perfect. Then it would count as concealment for other effects. That simplifies things.
I found it weird that I couldn't find any previous thread on Whiteout, as it's essentially HiPS as long as you supply the smoke.

"approximately equal in power to half a feat", sure.

Well be sure it's not "smoke" but mist of some sort and you're fine. It needs to be water based.
