To create a
scroll, a character needs a supply of choice writing materials, the cost of which is subsumed in the cost for scribing the
scroll-12.5 gp x the level of the spell x the level of the caster.
All writing implements and materials used to scribe a
scroll must be fresh and unused. A character must pay the full cost for scribing each spell
scroll no matter how many times she previously has scribed the same spell.
The creator must have prepared the spell to be scribed (or must know the spell, in the case of a
sorcerer or
bard) and must provide any material component or focus the spell requires. If casting the spell would reduce the caster's XP total, she pays the cost upon beginning the
scroll in addition to the XP cost for making the
scroll itself. Likewise, a material component is consumed when she begins writing, but a focus is not. (A focus used in scribing a
scroll can be reused.) The act of writing triggers the prepared spell, making it unavailable for casting until the character has rested and regained spells. (That is, that spell slot is expended from her currently prepared spells, just as if it had been cast.)
