I was going to create a character that revolved around a Stealth power. Basically it allows the user to become a pool of shadow, allowing him or her to pass through, over, under, or around any physical object without any difficulty. It gains all the perks of Cloak of Shadows as well. I looked through the Custom Powers List and didn't see anything like this, but if it's already been discussed I couldn't find it. My rough draft looks something like this:
Shadow Form -2
See in the Dark Perception rolls are not penalized by darkness.
Melt into the Shadows When in a reasonably sized shadow you gain a +2 to Hiding.
Shadow Form You become a shadow, granting you a +2 to Skulking when in a reasonably sized shadow. Any difficulties due to passing through physical barriers (door, window, fence) are reduced to 0. Others can opt to use Lore instead of Alertness or Investigation when attempting to locate you. You cannot manipulate physical objects in anyway while in Shadow Form
Quite as a Shadow You cannot be heard and cannot make any noise.
I was thinking about adding some kind of armor against physical attacks (guns, knives, and fists), but I am stuck between what makes sense and what is balanced. I also decided against altering your senses while in Shadow Form for better of for worse, just to keep it simple. Others can certainly modify this or add optional powerups but I'm trying to keep this a two refresh power so that Minor Talents can take this if they want.
The mechanics of actually changing into Shadow Form would be identical to changing into a Wereform.
