7 hp, +16 for fast healing. so 23 hp.
accounting for it's cold vulnerability, CMT just did 34 damage.
putting it at -11 hp. If it gets up, someone is manipulating the arena match. (Unless that's just the missile knocking it down and it getting up)
Plus, John Vaarth and colt act before it's fast healing acts the second time.
Also, does not john have evasion, making the 1/2 damage 0 damage?
Who's to say it's the average Pyrohydra?
I do all of this on my phone... I'm sorry if I'm slow or miss a post.
