Wait

To wait is to pass one turn. It may be done by using the s or . keys. Waiting works like any other action (such as taking off and putting back on your weapon), though obviously does nothing. Waiting is required to continue the effects of channeling spells like Searing Ray. Unless a status like Haste, Slow, or Statue Form modifies it, waiting lasts 1.0 decaAut.

Resting (with the regular 5 key) automatically waits until you regenerate health, MP, or find something interesting, like a monster. If you are at full HP and MP, it'll wait up to 100 turns.
