A Wizard may choose to read his or her Spellbook in order to recover one entire spell level, (or maybe a bracket of spell levels) at the cost of an amount of Focus.
- If Focus is too low, reading becomes too difficult and the spells cannot be replenished.
- Spellbooks cannot be read in combat.
- Reading takes several rounds, making it impractical for quick recovery.
- Resting recovers an amount of Focus per rest tick, but may leave the state below 100% if it has been severely drained.
