I suggest more varities in belt craftings? I could easily be similiar to the Medics belt, as a tools belt.
Suggestions:
Rogue belt: Has limited charges of various grenades, cannot be repaired. Requires to be a Rogue for use, perhaps a certain level, like the various already grenades. There is alot of creative options for the creators, it do not have to be grenades that already can be crafted or purchase from the -rogue command.
Necromancer Belt: Easily an extra tool, to summon extra Undeads, by use of the Animate dead spell, or other useful spells, i do not know enough within that school to suggest something.
Warrior Belt: Various combat improvement "spells", again, one time use, cannot be repaired. Can also have some protection values and AC attached to it.
I see alot of possibilities that can be added, to give more utilities in battle or RP. It is only the imagination that can add to this
I have faith in that creators can see a fair balance on how the belts should be created.. all of the above is suggestions, to give an idea of what could be made.
