Exit/Teleport can also let you escape battles.

Reflect can't reflect meteo or reflected spells. For example, An enemy has Reflect status and the whole party has Reflect status. Enemy casts Flare on itself. Reflect Status bounces the magic at your party and goes through their Reflect status, damaging them.

Also in this game, bad statuses can be cured by casting the spell on the affected character. For example, if a character has Toad status, casting Toad on that character will cure the status. While under "Pig" or "Toad" status, the spell "Pig" and "Toad" are the only spells you can cast.
