Reverse or Negate Healing can be a problem.
His moveset consists of some odd skills, such as a Death Countdown(3 CD, 42s), an AoE 45 Nature + Poison + Stun(3 CD, 43s), a single-target version of said skill, a 70 Special + Life Steal(which is useless because of his laughable Power stat), and a 55 Special with 100% Life Steal(again, useless). All of his stats are mediocre, and the less said about his trait, the better. Alpha Cliviast is a pretty average plant monster.
