Traits

Immutable Form. The archive guardian is immune to any spell or effect that would alter its form.

Magic Resistance. The archive guardian has advantage on saving throws against spells and other magical effects.

Spell Shield (3/Day). The archive guardian can counter a spell cast within 120 feet of it as a reaction. This works like the counterspell spell, except the guardian automatically counters any spell of 5th level or lower, and must make a check using its Constitution modifier for higher-level spells.
