Blooming Guardian

CREATURE 15

The pestilent blossoms adorning the antlers of a blooming guardian are most beautiful in moonlight, when they achieve full bloom and reveal their celestial glow. When blooming guardians near the end of their life cycle, they walk one final patrol of their forest as their ancient body decomposes into the understory.

Budding Siphon (aura, primal, stance, void)

20 feet. A blooming guardian is in a constant state of decomposition; to keep this entropy at bay, the flowers that cover their antlers continually siphon life from the surrounding area. All living creatures that enter or start their turn in the emanation take 6d4 void damage (DC 36 basic Fortitude save). At the start of their turn in any round that the blooming guardian deals damage with siphoning buds, they gain 10 temporary Hit Points, plus 2 temporary Hit Points for each creature damaged beyond the first since the blooming guardian's last turn, to a maximum of 20 temporary Hit Points.

Full Bloom (poison, primal, stance)

The flowers on the blooming guardian's antlers bloom, unveiling their brilliance as they eat away at their host. While in this stance, the blooming guardian's Strikes deal an additional 2d4 poison damage plus 5 persistent poison damage; on a hit, a target must succeed at a DC 36 Fortitude save or become Enfeebled 2. The blooming guardian takes 5 persistent poison damage as long as it's in Full Bloom.

Goring Charge

The blooming guardian Strides twice and makes an antlers Strike after either Stride. If the Strike hits, the blooming guardian deals an extra 2d12 bludgeoning damage, and the target takes a –2 circumstance penalty to its next Fortitude save against blossom siphon.

Wail of the Forest (primal, void)

Requirements The blooming guardian is in Full Bloom

Effect The blooming guardian confronts their mortality, causing their flowers to burst and spray their pollen. All creatures in a 40-foot cone take 10d10 void damage with a DC 36 Fortitude save. The blooming guardian then exits Full Bloom and can't enter it again for 1d4 rounds.

Critical Success No effect.

Success The creature takes half damage.

Failure The creature takes full damage and becomes Drained 1. Creatures that are Enfeebled lose that condition and increase the drained condition by the same value.
