Traits

Semi-Aquatic. Concavenator can enter any body of water and stay submerged upwards of 45 minutes.

Shark Mimic. When engaging in combat from the water, Concavenator has advantage on attack rolls. Additionally, Lunge gets an additional 4 (1d6) added to the total damage as well as an additional 10 ft. of range.

Riverbank Assaulter. Concavenator has advantage on initiative rolls when submerged.

Serpent's Lash. When an attack is made with the Concavenator's tail, a coin must be flipped. If it lands on heads, the target takes standard damage. If it lands on tails, the target suffers from one of the following effects at the DM's discretion: 

  • Stunned: Having been struck by the powerful whip of the Conca, the target will find themselves disoriented and reeling from the immense stinging pain.
  • Prone: The force of the lash came with such speed that the target did not have time to prepare, being knocked flat onto the ground and winded.
  • Envenomated: The potent venom lining the Concavenator's tailbarbs flows into the target's bloodstream. They suffer the poisoned effect, and additionally take 1d4 poison damage for the next three rounds unless they have an antidote.

Whip Cut. While Concavenator's body is resistant to slashing damage, the tail is not. If over 1/3 of the Concavenator's max HP is done in slashing damage against the tail, the whip-like extension will be cut off and prevent all tail-related attacks and effects.

 

Actions

Whip Crack. Concavenator lashes its tail in the air, letting out a loud boom. If a target is within 5 feet of the tail's tip at the time of the crack, they take 1d4 thunder damage, are deafened for two rounds, and stunned for one round unless interacted with, in which case they are only deafened.

Lunge. When the Concavenator is within 15 ft. of a target, it has the option to lunge. When lunging, the Concavenator quickly moves through the air, preventing opportunity attacks from everybody but the target. The target must succeed a DC 18 Strength saving throw or a DC 15 Dexterity saving throw to avoid being hit by the lunge. If they fail, the target takes 8 (2d6+2) piercing damage and is grappled. 


 

Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 8 (1d8+4) piercing damage.

Ripping Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 12 (2d6+4) slashing damage. [Applies bleeding, causing passive -2 health per round and an extra 1d4 flat damage received on every hit until DC 12 medicine check is passed.]

Whiplash. Melee Weapon Attack: +8 to hit, reach 15 ft., two targets. Hit: 12 (4d4+2) slashing damage.

Maul. Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 9 (2d6+4) piercing damage.

.

Reactions

Flail. If three or more opponents are within 15 ft. of the Concavenator, it has the option to thrash its tail around. Every target in the vicinity must roll a DC 14 Dexterity saving throw or deal with the Whiplash attack as well as possible side-effects of Serpent's Lash.

Description

"A beast resides in the rivers, one that does not take kindly to intruders in its waters. It feeds on our fishermen, stealing our haul... it's trying to starve us out." - Grimmjhi, Southern Port Village

The Concavenator is a medium-sized semi-aquatic dinosaur, often recognized by its conical, protruding teeth and shark-like appearance. Like the unholy spawn of a Thresher Shark and a Stingray, this beast's tail fades into a long, whip-like structure adorned in small barbs. Moderately strong arms and deceptively strong legs allow this predator to burst from the water and tackle prey, mauling it on the riverbank or dragging it back to the depths to drown. 

The Concavenator, while primarily solitary, may cooperate with other Concavenators when a large source of food is nearby. When herds pass by a body of water Concavenators reside in, they will synchronize with one another, communicating with thundering whipcracks to frighten their prey and lure them into the perfect ambushing zone. When the trap is sprung, all the Concavenators involved will lunge from their hiding place and attempt to secure their own kill, whether it is on land or in the water. 

Concavenator is not a species typically domesticated, as most tribes find them almost treacherous. These predators are extremely opportunistic, and offer no objection to eating their own kind. The species' habit for cannibalism paired with their poor reputation make it an unideal pet, though some fishermen who manage to thoroughly train these creatures proclaim there's almost nothing else they'd rather have with them out on the water.
