Monster Manual 2 Excerpts: Heroslayer Hydra
Quick summary: level 20 solo brute, has the Lernaen hydra vibe with growing new heads, and has x4 hit points.
Still pretty vanilla, like the other hydras, but growing new heads as the fight progresses (it eventually has 8 heads) and doing extra damage against creatures that mark it could make it play better than it reads.
It would have been cool if it could also grow a head each time it suffers a critical hit -- but maybe with 776 hp, you would expect too many crits and then somewhat crazy damage output.
