Ampoule Mastery
Source
Galactic Magic pg. 19
You have surpassed conventional spell ampoule science, allowing you to prepare one 3rd-level spell amp each day from your list of known spell amps using the ampoule expertise theorem. When you gain this theorem, you also add one additional spell to your list of spell amps that you can prepare.
At 18th level, you can prepare one 4th-level spell amp each day from your list of known spell amps; this exceeds the normal level limit for spell ampoules, though any 4th-level spells you add to your list of spell amps must still follow all other rules for creating spell amps.
You must have Ampoule Expertise to select this theorem.
