I have a player that I am working on making a race for. She did something I wasn't expecting during out game and as a result I turned her into an undead creature of darkness (evil campaign).
Sitting down with her, we are making her very susceptible to light, including light blindness (-2 RP), sunlight sensitivity (-2 RP), and sunlight powerlessness (-2 RP), Undead subtype (16 RP), Flight (4 RP), and Natural Attack - Wings (1 RP).
The wings are wings of shadow and as such it seems appropriate that they should function as touch attacks (also, she intends to use them to deliver touch spells like Shocking Grasp and Vampiric Touch). What do you think would be an appropriate RP cost to make her natural attacks target touch AC?
