Arthropod Etouma "Magic Eater"

Multi attack: The Magic Eater makes 2 claw attacks on its turn.

Pack Tactics: The Magic Eater has advantage on attack rolls against creatures if at least one other Etouma is within 5 ft of the target.

Magic Resistance: Magic Eaters have advantage on all saving throws against magic.

Magic Evasion: Upon succeeding any saving throw against a spell, they take no damage instead of reduced and can ignore all other ill effects of that spell.

Lightning Absorption: When it takes lightning damage, it will instead heal for the damage that would be dealt.

Draining Claw: +4, 1d8 + 2 slashing, 1d6 lightning (11). The target of this attack will have their magic drained away, roll 1d6 and the target loses one of their spell slots of that level as if they had cast a spell.
1-3: 1st level
4-5: 2nd level
6: 3rd level
If the target does not have the appropriate spell slot to drain, drain the next lowest spell slot they have available. If the target is out of spell slots, they will forget a random cantrip instead until their next short or long rest.

This attack does additional lightning damage equal to the level of the spell slot drained if successful. (1 if a cantrip is forgotten)
