Bloom Warden

Living Construction. The bloom warden regains 5 hit points at the start of its turn. If a bloom warden takes poison or necrotic damage, this trait doesn’t function at the start of its next turn. A bloom warden dies only if it starts its turn with 0 hit points and doesn’t regenerate. Lost or severed limbs regrow when the bloom warden reaches full hit points.

Verdant Purpose. Despite a bloom warden’s limited capacity for greater reasoning, it possess an uncanny knowledge for plants, gardening, and landscaping. Treat the bloom warden’s Intelligence (Nature) rolls as automatic critical successes.

Innate Spellcasting. A bloom warden's spellcasting ability is Wisdom (spell save DC 18). The bloom warden can innately cast the following spells
At will: druidcraft, plant growth
1/day: move earth

Multiattack. A bloom warden makes one Uproot and two Prune attacks.

Uproot. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 19 (2d12 + 6) piercing damage and the target is grappled (Escape DC 17). Until this grapple ends the bloom warden can't use Uproot on another target.

Prune. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 9 (1d6 + 6) slashing damage. If the bloom warden has the target grappled it makes these attacks with advantage.

Detain. One creature the bloom warden has grappled must make a DC 17 Constitution saving throw. On a failed save, the creature takes 38 (5d12 + 6) bludgeoning damage or half as much on a success. Creatures that are reduced to 0 hit points by this ability are stable.
