In the first round of a combat, the shapeshifter has advantage on attack rolls against any creature it surprises.
The shapeshifter can assume the appearance of any Medium (or smaller) humanoid or beast it has eaten. It also feels and sounds exactly like the victim, speaking the languages it knows. Only a successful DC 18 Wisdom (Insight) check will reveal it to be a fake.
The shapeshifter has advantage on saving throws against spells and other magical effects.
The shapeshifter regains 10 hit points at the beginning of each of its turns. It is only destroyed if it starts its turn with 0 hit points and doesn't regenerate.
The shapeshifter can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
The shapeshifter can make one attack with its bite and two attacks with tendrils that emerge from inside its body.
Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 18 (3d8 + 5) piercing damage.
