Action
Bite
Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 18 (2d12 + 5) piercing damage.
Action
Claws
Melee Weapon Attack: +9 to hit, reach 10 ft., one target. Hit: 14 (2d8 + 5) slashing damage. If the target is a creature, the target is grappled (escape DC 17). The grendel has two claws. While a claw grapples a target, the claw can attack only that target. When the grendel moves, any Medium or smaller target it is grappling moves with it.
Action
Multiattack
The grendel makes three attacks: one with its bite and two with its claws.
Action
Swallow
The grendel makes one bite attack against a Medium or smaller target it is grappling. If the attack hits, the target is swallowed, and the grapple ends. The swallowed target is blinded and restrained, it has total cover against attacks and other effects outside the grendel, and it takes 10 (3d6) acid damage at the start of each of the grendel's turns. The grendel can have only one target swallowed at a time. If the grendel dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 5 feet of movement, exiting prone.
Reaction
Bloody Rampage
When the grendel takes damage, it makes one attack with its claws against a random creature within its reach.
Special
Ambusher
In the first round of a combat, the grendel has advantage on attack rolls against any creature it surprised.
Special
Bloodthirsty Frenzy
The grendel has advantage on attack rolls against frightened creatures.
Special
Horrific Appearance
Any humanoid that starts its turn within 30 feet of the grendel and can see it form must make a DC 14 Wisdom saving throw. On a failed save, the creature is frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if the grendel is within line of sight, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the grendel's Horrific Appearance for the next 24 hours. Unless the target is surprised, the target can avert its eyes and avoid making the initial saving throw. Until the start of its next turn, a creature that averts its eyes has disadvantage on attack rolls against the grendel.
Special
Shadow Stealth
While in dim light or darkness, the grendel can take the Hide action as a bonus action.

Special
Brutal Surge (Su)
When Grendel expends mythic power to add a surge die to an attack roll, he also adds a surge die to that attack's damage roll. This is not an action and does not require him to expend any additional uses of mythic power to use this ability.
Special
Gruesome Dismemberment (Ex)
When Grendel successfully holds a creature he has grappled, he may expend one use of mythic power to attempt to dismember that creature. He attempts a grapple check; if successful, his target takes double his normal claw damage and the attack pulls off one of the target's legs or arms. The target is sickened until it receives magical healing (or until it recovers to full hit points by natural means), and takes 2d6 points of bleed damage each round. A creature with only one an arm cannot perform actions requiring two arms or two hands. A bipedal creature with one leg missing cannot walk or run; it can crawl or hop, but is denied its Dexterity bonus against all opponents. A quadrupedal creature with one leg missing is reduced to half normal speed. At the GM's discretion, creatures with more than four legs affected by this attack may be able to move at normal speed.

This horrific, hulking beast is only barely humanoid, with large claws, warty skin, and a terrifying visage.
A whirlwind of teeth and claws, grendels are spawned by ketta and used by them to exact revenge upon all that is good. As fiends, they have an innate hatred of song and revelry; the grendel particularly so. It strikes in the dead of night, murdering as many humanoids as it can, greedily gulping down those it can eat quickly and carrying off any others for devouring later. These victims are shared with the ketta that spawned it, and in this regard the grendel regards the ketta as its “mother.”
