Trampling Charge. If the thessalgorgon moves at least 20 feet straight toward a creature and then hits it with a gore attack on the same turn, that target must succeed on a DC 16 Strength saving throw or be knocked prone. If the target is prone, the gorgon can make one attack with its hooves against it as a bonus action.
Gore. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 18 (2d12 + 5) piercing damage.
Hooves. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 16 (2d10 + 5) bludgeoning damage.
Petrifying Breath (Recharge 5–6). The thessalgorgon exhales petrifying gas in a 30-foot cone. Each creature in that area must succeed on a DC 13 Constitution saving throw. On a failed save, a target begins to turn to stone and is restrained. The restrained target must repeat the saving throw at the end of its next turn. On a success, the effect ends on the target. On a failure, the target is petrified until freed by the greater restoration spell or other magic.
Description
The thessalgorgon is a hybrid of a thessalhydra and a gorgon. It has the scaled, lizardlike body of the thessalhydra, eight snakelike heads, and a bull’s head in the middle of the snake heads. The entire body is covered in thick, metallic scales that are a coppery green in color. A thatch of green-black hair covers the top of the bull’s head, the chest, and upper forelegs.
Combat: Each head attacks independently and bites for 1d6 points of damage plus an additional 1d6 points if the victim fails a saving throw vs. poison. The main mouth bites for 2d6 points of damage plus an additional 2d6 points if the victim fails a saving throw vs. poison.
Four times per day, the thessalgorgon can breathe out a cone of petrifying gas measuring 5 feet at the mouth, 60 feet long, and 20 feet wide at the end. Victims who fail their saving throws vs. petrification are immediately turned to stone.
Thessalgorgons are immune to petrification and all acids.
A fringe head can suffer 12 points of damage before it is severed. Damage done to heads does not affect the overall hit points of the monster. Severed heads are regenerated in 12 days.
Fringge head AC is 20
