Evocation adept

Prerequisite: Spellcasting or pact magic feature

You have advanced your ability to summon forth magical energy.

You learn one evocation cantrip of your choice from any class's spell list.

In addition, choose one 1st-level evocation spell from any spell list. Using this feat, you can cast the spell once at its lowest level, and you must finish a long rest before you can cast it in this way again. You can also cast this spell using your regular spell slots.

Your spellcasting ability for these spells is the same as that of your own class.

Furthermore you also gain an amount of evocation points equal to half your character level rounded up + your proficiency modifier. When casting an evocation spell of any level you can expend one or more of these points to create one or more of the following effects:

• The range of the spell increases by 5 feet per expended point. This only affects spells that already have a range of at least 5 feet.
• The range of the spells area of effect increases by 5 feet. Only one point can be expended to cause this effect per spell. This only affects spells that already has an area of effect. 

You regain all your expended points when you finish a long rest.
