Changes

Once you’ve cast a prepared spell, you can’t cast it again until you prepare it again. (If you’ve prepared multiple copies of a single spell, you can cast each copy once.) If you’re a [[SRD:Bard|bard]] or [[SRD:Sorcerer|sorcerer]], casting a spell counts against your daily limit for spells of that [[SRD:Spell Level|spell level]], but you can cast the same spell again if you haven’t reached your limit.

To cast a spell, you must concentrate. If something interrupts your concentration while you’re casting, you must make a [[SRD:Concentration Skill|Concentration]] check or lose the spell. The more distracting the interruption and the higher the level of the spell you are trying to cast, the higher the [[SRD:DC|DC]] is. If you fail the check, you lose the spell just as if you had cast it to no effect.
