Specifically, I wanted to see what you guys would want for a new boss dungeon (Firestorm Citadel + Vanaduke, Ironclaw Munitions + Roarmulus Twins, etc.) and its boss.
If OOO were making a new concept or a new boss to its game, what would you want to see from it? Think about the themes of it, concept of the boss, et cetera. Let your imagination unleash!
I have no real idea for a new boss, but my current favorite boss is the RT. Why? It is the only boss that actually requires some kind of teamwork. Even Vana is mainly blitz blitz blitz blitz next phase water blitz blitz blitz repeat.
So a new boss could be puzzle-like, or at least require a huge lot of teamwork. Something swarm-related sounds perfect for this, having the players cooperatively fighting swarm sources and such stuff.
Megalodon as a boss. With jellyfish like polyps, beast themed sting rays, ranged attacking beast themed pufferfish, and beast anglerfish.
To compliment angler fish one of the levels can use a pitched black layout. Or something roughly similar to apocrea. Megalodon itself needs to be beast/construct for obvious reasons. Just let some high brained gremlin alter it or something.
One thing this game never goes into is where it gets its water. There was even waterfalls in a level before yet no one questioned it. Probably due to all the shock spasms a certain turtle gave them. *shrug*
Well the obvious one would be some sort of resolution to the artifact/Herex/Tinkinzar subplot.
Although I've always wanted a fiend dragon. All the bosses (except Snarby I think) have some sort of mini army at their side as you fight them. So I really want a boss that needs no help and can wipe the floor with a group of unprepared knights with a casual flick of his tail. Something that you can't beat by launching yourself at it like a knight shaped missile, flailing a sword while you do so. A strategic fight where you have to wait and watch for tells, looking for openings to counter-attack, instead of a chaotic mass of minions and projectiles.
