  • Keen Sight. The grim roc has advantage on Wisdom (Perception) checks that rely on sight.
  • Sunlight Sensitivity. While in sunlight, the grim roc has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.
  • Turn Defiance. The grim roc has advantage on saving throws against effects that turn undead.


  • Multiattack. The grim roc makes three attacks: one with its beak and two with its talons.
  • Beak. Melee Weapon Attack: +16 to hit, reach 10 ft., one target. Hit: 32 (5d8 + 10) piercing damage.
  • Talons. Melee Weapon Attack: +16 to hit, reach 5 ft., one target. Hit: 27 (5d6 + 10) slashing damage, and the target is grappled (escape DC 20). Until this grapple ends, the target is restrained, and the grim roc can’t use its talons on another target.
  • Evil Eye from the Sky (Recharge 2-3). The roc shoots green rays out of its eyes in a 90-foot line that is 5 feet wide. Each creature in that line must make a DC 17 Dexterity saving throw, taking 45 (10d8) necrotic damage on a failed save, or half as much damage on a successful one.


A bright flash of green light can be seen up in the mountains. All the villagers down below know a grim roc is in the area. This undead monster is one of the most dangerous creatures in the world. Its enormous shadow and glowing green eyes strike fear into the hearts of those who dwell in the mountains.

Winged Horror. Malevolent necrotic energies reanimated these creatures. The massive evil bird can destroy a city on its own. It simply annihilates everything in its path.

Distant Peaks. Grim rocs live high up in the mountains and can take over large portions of the world. Only the bravest adventurers will go on quests to deal with this menace.

Undead Nature. The grim roc doesn’t require air, food, drink, or sleep.
