Arcane Surge (WIS)

All spell casters have arcane surges that they can use to empower their spells. The number of arcane surges available is equal to the caster's spellcasting ability modifier (minimum of 1). One arcane surge is recovered after a short rest and all are recovered after a long rest. When a caster takes their turn they may take a bonus action before casting to use one of the following arcane surge abilities:

• The spell can benefit from a higher effect, as if the spell slot was one level higher (up to 10th-lvl)
• The spell's attack(s) can be rolled with a +2 modifier
• The spell's DC gains a +2 modifier
