Prerequisite: You must be at least 5th level to select this discovery.
Benefit: Once per day when you prepare spells, you may treat any one of your open
spell slots as if it were two spell slots that were two spell levels
lower. For example, a 9th-level Wizard can split a 5th-level slot into
two 3rd-level slots, preparing fireball and lightning bolt
in those 3rd-level slots. For all purposes, the two lower-level slots
are treated as that lower level (so the split 5th-level slot used for a fireball
has a DC as if it were in a normal 3rd-level slot). Splitting a
2nd-level slot lets you prepare two additional cantrips (which you can
cast over and over, just like normally prepared cantrips). This
discovery has no effect on cantrips or 1st–level spells.
Special: You may select
this discovery multiple times; each time you select it, you may split
another spell slot when you prepare spells. You cannot split a slot that
you created by splitting a higher-level slot.
