Spellbonus clasps of some sort would be a kewl addition. ..unless they're already out there but I haven't stumbled across any info about them yet hehe.
Also adding spellbonus/healbonus/stabdam as avatar light options would be handy for some people. (I mean as the 2 main functions of the light, not add-ons like protection from evil etc, as that would probably be giving out too much power).
