In Complete Arcane there's an Epic feat called (I believe) Staff Master. The prereqs are Craft Staff and some high skill. I think it's 30 ranks in Spellcraft, but I'm not sure.
Anyway, what this feat does is let you burn your own spell slots to power a staff. So you can cast the spell(s) the staff provides using your own slots of the same or higher level.
I looked at this and thought: Not only does that seem pretty lame for an epic feat, I think that's how a staff should work anyway. With the RAW, a staff isn't much better than a wand, really. It can store higher-level spells and might have other abilities on it, but if the PC is crafting it, it's basically like having several wands duct-taped together. I've always thought a staff should be better than that, and that it should (at least potentially) not run out of charges. You don't see Gandalf chasing away the nazgul and then shrugging and tossing his staff in the trash because it's out of charges.
So I ask: just how bad would it be to let any caster who can use a staff power it with their own spell slots?
