Spells and concealment.

[Question]

Lets say the target has 50% concealment.

You fire a "direct hit" spell......such as chain lighting. Do you need to roll for concealment? Or does it ONLY apply to spells that require either touch or ranged touch attacks?

Or does it ONLY apply to spells that require either touch or ranged touch attacks?

Yes.

Caveat: You still have to be able to target the creature, the square he is in, or legitimately have his square in the AoE.

One more thing: There is either "Concealment" or "Total Concealment". They are different than "50% miss chance". Which/what do you mean?

Lets say the target has 50% concealment.

You fire a "direct hit" spell......such as chain lighting.

Presuming by 50% concealment, you mean total concealment, then you cannot choose a totally concealed target as part of the chain lightning.

You must be able to see or touch the target, and you must specifically choose that target.

...or invisibility. {EDIT} Huh, I had not realized that invisibility grants total concealment. I had thought it was a separate condition that just happen to have the same 50% miss chance. ...But there's the phrase "total concealment" in the invisibility condition description. Huh.


And all of this assumes the wizard in question has no means of seeing the target.

We've run into this in our game, with displacement or mirror image, vs a lightning bolt.

As long as they know (or can guess) what square they are in, lightning bolt (or another line or area attack) trumps concealment, so there is no concealment roll.
