How Much of a Limitation?

[Spideyguy]

Steve,

I have a darkness based character who has taken the limitation "Power only works at 1/2 effect during daylight" with a limitation of -1.

Does this seem reasonable to you, or should this be more/less of a limitation? I always have a hard time adjudicating custom limitations, and would appreciate your opinion.

Thanks!

I'd buy the power in two parts. Figure out how big you want it to be at night. Buy half that unLimited. Buy an equal amount with a -1 "Not During The Day."
