Arcane Discharge. When an aranaphage dies, it explodes in a surge of partially-digested magical energy. Each creature within 5 feet per feed score must make a DC 14 Dexterity saving throw, taking 3 (1d6) force damage per feed score on a failed save, or half as much on a successful save. for 1 minute afterwards, the affected area is awash with volatile magic. A creature that starts its turn in the affected area takes 7 (2d6) force damage.
Hunger. Each time it feeds in combat, it regains hp equal to twice the level of the spell it ate and increases its Feed score by 1. The arcanaphage can't have a feed score higher than8, and its feed score reduces 1 each time it finishes a long rest
Ingest magic. At the start of each of the arcanaphage's turns, each creature within 30 feet of it that is currently maintaining concentration on a spell must make a DC 14 Constitution saving throw. On a failed save, the creature's spell ends and the arcanaphage feeds.
magic Immunity. The arcanaphage is immune to damage from spells. It has advantage on all other magical effects.
Multiattack. The arcanaphage makes two tentacle attacks.
Tentacle Attack. Melee Weapon Attack: +6 to hit, reach 5 ft., 1 target. Hit: 13 (2d8 + 4) [bludgeoning] damage.
Voracious. The arcanaphage's tentacles glow when a spell is cast within 30 feet of it, countering the spell. this reaction works like the counterspell spell, except the arcanaphage must always make a spellcasting ability check, no matter the spell level. Its ability check for this is +5. If it successfully counters the spell, the arcanaphage feeds.
Description

Arcanaphage are commonly found in places imbued with magic, their colorful skin rhythmically pulsating as they graze on arcane energies.
Magivore. The arcanaphage diet consists exclusively of magic. It has no mouth; it feeds by absorbing nearby magical energy into a series of ropy tentacles that run the length of its body. With enough time, an arcanaphage can slowly slurp all the power out of magical objects, traps, or spells permanently imbuing an area . Most arcanaphage are about the size of a large dog, though especially well-fed specimens the size of draft horses have been reported.
Docile Unless Angered. If left to feed undisturbed, an arcanaphage typically ignores its surroundings. However, when it feels Threatened or when food is scarce and it senses magic nearby, it viciously attacks.
