Counter Mage

Spellcasting. The abjurer is a 7th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 13, +5 to hit with spell attacks). The abjurer has the following wizard spells prepared:

Cantrips (at will): blade ward, mending, message, ray of frost

1st level (4 slots): absorb elements,* mage armor,* snare,* shield*

2nd level (3 slots): lesser restoration,* protection from poison*

3rd level (3 slots): counterspell,* dispel magic,* remove curse*

4th level (1 slots): private sanctum,* freedom of movement*

*Abjuration spell of 1st level or higher

Arcane Ward. The abjurer has a magical ward that has 17 hit points. Whenever the abjurer takes damage, the ward takes the damage instead. If the ward is reduced to 0 hit points, the abjurer takes any remaining damage. When the abjurer casts an abjuration spell of 1st level or higher, the ward regains a number of hit points equal to twice the level of the spell.

Quarterstaff. Melee Weapon Attack: +1 to hit, reach 5 ft., one target. Hit: 2 (1d6 − 1) bludgeoning damage, or 3 (1d8 − 1) bludgeoning damage if used with two hands.

Wand of Dispel Magic.  While holding the wand, you can use an action to expend 1 or more of its charges to cast the dispel magic spell (save DC 15) from it. You can cast a higher level version of the spell  by expending one additional charge per level.

This wand has a maximum of 7 charges. It regains 1d6 + 1 expended charges daily at dawn. If you expend the wand's last charge, roll a d20. On a 1, the wand crumbles into ashes and is destroyed. (see homebrew item of same name)
