How about a feat for DnD Next?
Extended Invisibility
You stalk the shadows and the bright areas, but you make sure you are not seen in the best ways possible…
- Gain a +1 bonus to dex, to a maximum of 20
- When you perform an action that causes you to lose your invisibility as per the spell, you do not lose invisibility until the tend of your next turn.
Thoughts?
