...and wakens a MASSIVE four headed hydra that lives in the volcano. It quickly eats her and then goes after the party.
My basic concept is to make each head (since each head is large enough to take a chunk out of a Huge fire titan) an elite monster. One of the heads will be an artillery, and one of the heads will be a lurker, pouncing out of the lava every other round to harry the party. For the other two heads, I am leaning towards brute and either soldier or controller.
Any thoughts on general abilities? I've started to work on a couple of the heads, but I'd be fascinated to see how you might approach this design.
Sounds cool.
When you say each head is an elite monster, are they still attached to the hydra body by a neck with a definite length or are we talking primordial hydra whose body is made of living fire able to move its heads around with impunity?
The environment is probably going to be a big factor in this encounter, I take it there will be a large area of larva, but is there going to be anything else that might be note worthy?
Is this forge going to be in the same encounter?, if it is then you could have some sort of skill challenge for it to have an effect on the hydra.
This sounds similar to a creature I used a long time ago that had 3 independent heads connected to a body by ethereal chords. I used elites for that and it worked very well, so the concept is sound.
I will see what I can come up with.
