Manipulate Magic

You’ve learned how to exert your will on your spells to alter how they function, allowing you to overcome many magical defences:

• When you cast a spell that deals damage, you can expend use of this option to change that damage type to another. You can only do this as the spell is cast, and only before knowing the results of any roll.
• When you cast a spell that requires a saving throw, you may change the type of save required. For example, if you were to cast fireball, you could force creatures withing range to make a wisdom save rather than a dexterity save. You can only do this as the spell is cast, and only before knowing the results of any roll.

You cannot use this ability more than once a turn, and can only choose one effect to apply to a spell.

You can use this ability a number of times equal to your proficeny bonus.
