Arcane Befuddler - Turn your wizard's counterspell into a fireball centered on themself (Patreon)

CR 2 and 3 feys, here to annoy you in your day.

These tiny things appear when counterspells are out of control, and make sure to make magic even more chaotic. Very fun to throw at a party full of spellcasters.

Oh yes, they also slap you with mage hand.
