Lightning Absorption. Whenever Brin is subjected to lightning damage, it takes no damage and regains a number of hit points equal to the lightning damage dealt.
Mobility. Brin can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Vorpal weakness. If Brin’s head is severed from the masses, such as by a vorpal sword, all three masses immediately die.
Multiattack. Brin makes six slam attacks. If both attacks hit a Medium or smaller target, the target is grappled (escape DC 14), and Brin uses its Engulf on it.
Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.
Engulf. Brin engulfs a Medium or smaller creature grappled by it. The engulfed target is blinded, restrained, and unable to breathe, and it must succeed on a DC 14 Constitution saving throw at the start of each of the mound's turns or take 13 (2d8 + 4) bludgeoning damage. If Brin moves, the engulfed target moves with it. Brin can have up to three creatures engulfed at a time.
