Enrooted. Samorost can use its bonus action to enroot itself into the ground at the start of its next turn. While enrooted, Samorost’s movement speed is reduced to 0, its AC is increased to 18 against ranged attacks and all damage dealt to it is halved. Samorost can use its bonus action to end the Enrooted condition.

Each time Samorost would be forcibly moved by an effect while Enrooted, it makes a DC 16 (or higher depending on the effect’s ordinary DC if it has one) Strength saving throw, losing the Enrooted condition on a failure.  

If a creature is grappling Samorost, they can spend half of their maximum movement to end its Enrooted condition.

Crushing Roots. Creatures restrained by Samorost’s abilities take 15(2d8+6) bludgeoning damage at the start of each of their turns. A creature can use their action to attempt to escape or rescue a creature within reach (Escape DC 19).

Giga Drain. Samorost can use its bonus action to choose a creature restrained by its abilities. That creatures takes 9(2d8) necrotic damage and Samorost regains Hit Points equal to the damage dealt 

Burn and Wither. If a creature restrained by Samorost’s abilities takes fire or necrotic damage, Samorost takes equal amount of that damage as well and the restrained condition ends for the creature.
