There should be 5 caster equipables:
- Wand (ranged, one handed)
- Staff (ranged, two handed)
- Quarterstaff (melee, two handed)
- Scepter (melee, one handed)
- Focus (off-hand)
We have 3 of those.
Remember the Hammers faking quarterstaves the Bandits and Renegades had?

I say we could make those real 'Quarterstaves':
* Maximum damage range: 6 - 27.
* Damage type: Depending on req (caster attributes).
* Attack rate: 1.75 seconds.
* Modifiers: Inscription slot, Quarterstaff Caps (name prefix) and Quarterstaff Wrapping (suffix).
Scepter
* Maximum damage range: 7 - 21.
* Damage type: Depending on req (caster attributes).
* Attack rate: 1.33 seconds.
* Modifiers: Inscription slot, Scepter Pommel (name prefix) and Scepter wrapping (suffix).
The Mesmer rapier would be a 'scepter' looking like a sword and with slashing damage.
A chaos edge could be similar, but with chaos damage.
