Immutable Form. The bostik is immune to any spell or effect that would alter its form.
Magic Resistance. The bostik has advantage on saving throws against spells and other magical effects.
Consume Life. As a bonus action, the bostik can target one creature it can see within 5 ft. of it that has 0 hit points and is still alive. The target must succeed on a DC 10 Constitution saving throw against this magic or die. If the target dies, the bostik then regains 10 (3d6) hit points.
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 8 (2d6 + 2) piercing damage.
Unarmed Strike. Melee Weapon Attack: +3 to hit, reach 20 ft., one target. Hit: 5 (1d6 + 2) bludgeoning damage. Instead of dealing damage, the bostik can grapple the target and drag the creature into the bostik's space (escape DC 14).
Bostiks are constructed golems made of clay or any other resource that is proper 'golem-making material', they are completely stationary and have long winding arms that can stretch up to 20 feet and contort in unnatural ways. The bostik also has a large gaping mouth with razor-sharp teeth. Bostiks are usually created to protect things like doorways and chests. They can also be stuck onto walls or ceilings.
