Okay, how's this sound for an encounter?
PCs finally track down the lair of the Necromancer sometime after he's murdered his former master(and master of one of the PCs). They get on a flying ship to travel to his stronghold, which turns out to be an old laboratory of the dead master's former master. New session begins with them fully rested having just reached the lab.
They find the primary entrance impassable, and so have to go in through the back way, working their way through a magical vault only that PC can open, then have to cross through a trap encounter or two. They make their way to the lab, where they find the Necromancer putting the finishing touches on his creation, a massive dinosaur fossil golem with T-rex heads for hands I've been hinting at for a while. With a twist: it's made using the rules for
Construct Armor. He dons the armor and the fight begins.
Phase 1:
They fight the necromancer in armor. Lesser skeletons are summoned in small waves. Nothing powerful, just a distraction. He fights guardedly, trying to protect himself from attacks.
Phase 2:
As the players weaken the armor to near breaking, the necromancer casts a spell and the armor gets teleported into a dome of some type in the ceiling(maybe one made of some kind of translucent gem). There are four gems in the ceiling. As a full round action, the necromancer activates one, expending its power to summon a wave of monsters. As the PCs deal with the monsters, the necromancer heals the golem a bit each round. He only stops the healing to activate another gem, so they have to burn down adds quickly.
If it reaches full health, go back to phase one. Otherwise, phase 3 begins as soon as the final wave is dispatched.
Phase 3:
The necromancer in dino power armor descends once again and the fight resumes at whatever HP he made it to. His AC is lower, but he's attacking more recklessly, and more powerfully.
Phase 4:
Just as the power armor dies the necromancer teleports out to a platform across the room and summons his
Eidolon, a quadruped base form looking like a skeletal horse but with a twist. Just like the PC summoner Mystic Theurge's eidolon, he benefits from a trio of evolution enhancing gems I've home-brewed into the game. The final ability granted by the gems is the power to sacrifice his own life force(and entangle himself in chains) to unleash a powerful sonic attack on his foes(I'm kinda patterning that on Anima from FFX in my mind). The Necromancer then begins blowing summon spells each round to try to bring down the PCs. I'm suspecting that his PC counterpart will have to do the same while the Paladin/Holy Vindicator PC tries to bring down the Eidolon and the Necromancer himself with the GMPC companion doing whatever the other two decide is best.
So, what do you think? Any suggestions to make it more epic?
