Corrupted Traits
Corrupting Aura. Creatures within 10 feet of the Corrupted Golem Sentinel at the start of their turn must succeed on a DC 13 Constitution saving throw or take 5 (1d10) necrotic damage. If a creature fails this saving throw by 5 or more, they also gain a temporary mutation (use the Corruption Mutation Table) lasting 1 hour.
Arcane Disruption. When the Corrupted Golem Sentinel takes damage from a spell, the caster must succeed on a DC 13 Constitution saving throw or suffer the arcane backlash, taking 5 (1d10) force damage.
Magic Resistance. The Corrupted Golem Sentinel has advantage on saving throws against spells and other magical effects.
Multiattack. The Corrupted Golem Sentinel makes two Slam attacks.
Slam. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 9 (1d10 + 3) bludgeoning damage.
Arcane Discharge (Recharge 5–6). The Corrupted Golem releases a burst of corrupted magical energy in a 15-foot radius. Each creature in that area must make a DC 13 Dexterity saving throw, taking 13 (3d8) necrotic damage on a failed save, or half as much damage on a successful one. Creatures failing this save by 5 or more gain a temporary mutation for 1 hour as described in the Corruption Mutation Table.
