Psi-Like Abilities: At will - biofeedback (damage reduction 4/-*), energy adaptation (Manifesting time: Immediate action*), inertial armor (AC 7*). Manifester level 8th. The save DCs are Charisma-based.

*Includes augmentation for crystal sunflower's manifester level.

Reach (Ex): The crystal sunflower has an extended reach with its root stab. Its normal reach is doubled for this attack; giving a Medium crystal sunflower a reach of 10 feet and a Large Crystal sunflower a reach of 20 feet.

Root Stab (Ex): The crystal sunflower's primary attack is to stab with a sharpened root from under the ground. Unless the target has a means of seeing through the ground or has the tremorsense special quality, treat this attack as if the attacker is unseen. The target cannot use its Dexterity bonus (if any) to Armor Class, and the crystal sunflower gains a +2 bonus on the attack roll.

Seed Burst (Ex): Up to three times a day, the crystal sunflower can expel seeds from its head with the same effects as the swarm of crystals power. The damage done by this attack is 3d4 with no saving throw.

Crystal sunflowers attack creatures as a means for self-fertilization. They use their seed burst and root stab to kill passing creatures and then drag the bodies into the ground for food. When possible, crystal sunflowers use their Psionic Weapon feat to deal extra damage in melee.
