Cractalus (Cactus Greatknight)

False Appearance. While Cractalus remains motionless, it is indistinguishable from a regular cactus.

Brave. Cractalus has advantage on saving throws against being frightened.

Multiattack. Cractalus makes four Thorn Blade attacks.

Thorn Blade. Melee Weapon Attack. +6 to hit, 5 ft., one target. Hit: 13 (1d10+4) piercing damage.

Mind Bombardment. Cractalus chooses one target within 120 ft. of it. The target must make a DC 17 Intelligence check or take 11 (2d10+2) psychic damage.

Plasmweb. Cractalus fires a web made of electrified plasma at a target within 90 feet. The target must succeed on a DC 17 Dexterity throw. On a fail, the target is restrained and takes 12 (4d6) lightning damage. On a success, the target takes half as much damage and is not restrained.

Vestigal Drain (3/day). Cractalus closes his two false eyes and opens his one true eye, and blasts his foe with the power of wither and rotting of plants. The target must make a DC 22 Wisdom save. On a fail, the target is stunned for an hour and takes 205 (20d20+5) necrotic damage. On a success, the target is stunned for a week and takes 405 (40d20+5) necrotic damage.

Parry. Cractalus adds 2 to its AC against one melee attack that would hit it. To do so, the knight must see the attacker and be wielding a melee weapon.

Teleport. Cractalus teleports to any place in the multiverse that isn't magically guarded against teleportation.
