Vessels
How it's going to work:
- Staves are vessels for power. You can store extra mana in them, and use it to produce various useful effects and/or to enhance your spells.
- Example: the Staff of Force can expend mana to make the staff's melee strike inflict force (siege) damage, and/or a massive push effect; it can impart the same to any targeted spell. It can create force shields and walls to protect you.
- Orbs are vessels for concentration. You can multiply the effect of your Focus and Concentration when casting through an orb.
