You can use spell points to create one slot of each level of 6th or higher. Spells of 6th level and higher are particularly taxing to cast. You can’t reduce your spell point total to less than 0, and you regain all spent spell points when you finish a long rest. You expend a number of spell points to create a spell slot of a given level, and then use that slot to cast a spell. Instead of gaining a number of spell slots to cast your spells from the Spellcasting feature, you gain a pool of spell points instead. Cantrips don’t require slots and therefore don’t require spell points. The Spell Point Cost table summarizes the cost in spell points of slots from 1st to 9th level. In this variant, each spell has a point cost based on its level. Spell points give a caster more flexibility, at the cost of greater complexity. With this variant system, a character who has the Spellcasting feature uses spell points instead of spell slots to fuel spells.
One way to modify how a class feels is to change how it uses its spells. Spell Points Home Collapse All Spell Points
