Every spellcaster has a reserve of spell points based on class and level, and also gain bonus spell points from a high ability score. The caster spends a number of spell points appropriate to the spell's level to cast the spell.
- A spellcaster who normally prepares his spells is now setting his list of spells known for the day. He can cast any combination of his prepared spells each day.
- A spellcaster who cast all his spells spontaneously doesn't have to prepare spells. He can cast any spell he knows.
- A spellcaster who can cast a limited number of spells spontaneously are always treated as having those spells prepared without spending any spell slots to do so.
- A spellcaster who normally receive bonus spells form a class feature can instead prepare extra spells of the appropriate level, domain, and/or schools. He doesn't get any extra spell points.
Metamagic:
A spellcaster need not specially prepare metamagic versions of his spells, he can apply a metamagic effect at the time of spellcasting and must pay for the adjusted spell level(*). This does not increase the casting time. The normal limit for maximum spell level applies.
*) Variant: without any additional cost, 3/day.
