Zouyu 2014
CR 6 monstrosity
Huge monstrosity, chaotic good
The zouyu is capable of incredibly fast long-distance travel. When traveling at a fast pace, the zouyu can run 310 miles per day.
The zouyu has advantage on Wisdom (Perception) checks that rely on sight or smell.
If the zouyu moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 15 Strength saving throw or be knocked prone. If the target is prone, the zouyu can make one bite attack against it as a bonus action.
Actions
The zouyu uses Alter Luck. It then makes three attacks: one with its bite and two with its claws.
Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 16 (2d8 + 7) piercing damage.
Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage.
The zouyu flicks its vibrant, multi-stranded tail and alters the luck of one creature it can see within 30 feet of it, choosing one of the following luck options. The zouyu can't target itself with Alter Luck.
- Bestow Luck. The target has advantage on the next ability check, attack roll, or saving throw (zouyu's choice) it makes before the end of its next turn.
- Steal Luck. The target must succeed on a DC 15 Wisdom saving throw or have disadvantage on the next ability check, attack roll, or saving throw (zouyu's choice) it makes before the end of its next turn. If the target fails the saving throw, the zouyu has advantage on one attack roll or saving throw it makes before the start of its next turn.
