Warforged Wizard

Magic Resistance. The warforged wizard has advantage on saving throws against spells and other magical effects. Magic can’t put it to sleep.

Spellcasting. The warforged wizard is a spellcaster and ignores material and verbal components of spells. Its spellcasting ability is Intelligence (spell save DC 15, +4 to hit with spell attacks). It regains its expended spell slots when it finishes a short or long rest. It knows the following spells:

Cantrips (at will): fire bolt, mage hand, minor illusion, prestidigitation, 

3rd level (3 slots): fireball, counterspell

Multispell. The warforged wizard has two actions with which to cast spells, one of which must be a cantrip.

Fire Bolt (Cantrip). Ranged Spell Attack: +4 to hit, range 120 ft., one target. Hit: 11 (2d10) fire damage. A flammable object hit by this spell ignites if it isn't being worn or carried.

Fireball. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 28 (8d6) fire damage on a failed save, or half as much damage on a successful one. The fire spreads around corners. It ignites flammable objects in the area that aren't being worn or carried.

Counter. When a creature the warforged wizard can see casts a spell targeting the warforged wizard, the warforged wizard can cast counterspell without using a spell slot.
