You can create mystic potions.
Prerequisite: Mystical Spellcasting (2nd Level)
Benefit: You can create a potion of any spell of 3rd-level or lower that you know and that targets one or more creatures. Brewing a potion requires a Laboratory (see Chapter 1: Character Creation), and takes a number of hours equal to the spell’s level + the caster level of the spell. When you create a potion, you set the caster level, which must be sufficient to cast the spell in question and no higher than your own effective caster level. You make any and all choices about the spell’s effects at the time of brewing the potion.
The Purchase DC is 17 + the spell’s level + the caster level of the potion (whatever you decide to set it at) for the materials you need to create the potion. This cost is in addition to the costs for any and all material components necessary for the spell itself.
Within any given seven-day period, the number of mystical items you can make is limited by the total levels’ worth of spells in them. This includes scrolls, potions, arms, and wands. A 4th-level spell counts as four levels’ worth, for example, and weapon enhancements count as 1 spell level per +1 equivalent. You cannot create more levels worth of spells in 7 days than your Constitution modifier x4. For example, if you have Constitution 18 (+4), then you cannot make more than 16 levels worth of items in one seven-day period.
