I wish my Geckomen race to have low-light vision - that is, the ability to see very well in very dim light (such as starlight) and see farther in limited light (such as torchlight), but not in absolute darkness. How would this be handled in game terms? How many powers would this be worth?
I always found low-light vision difficult to arbitrate in 3.5, and avoided it in ACKS. That said, the best mechanics I know of are those in the D20 SRD.
If you want to use it, I’d say its worth 1 custom power rather than 2. Unlike infravision, it doesn’t let you see without any light whatsoever, making it less overpowering for thieves and assassin types in dark dungeons.
I’ll use the D20 SRD then, thanks!
