Since the Spiral Knights are, well, knights, shouldn't they be fighting dragons at some point? Now, I would imaging that a dragon boss would have the following properties:
Damage Type:
Piercing damage (bite)
Normal damage (tail swipe), good chance of causing strong stun
Elemental damage (fire breath), good chance of causing strong fire
Strong Resistances:
Piercing (due to scale armor)
Elemental (hey, it's dragon armor!)
Immune to Fire
Weaknesses:
Shadow damage
Neutral resistances:
Normal damage
Drops:
Dragon Key (token)
Dragon Scale (material)
Pre-boss levels:
Cavernous, with elaborate puzzles involving spikes, buttons, switches, and gates.
Boss Fight:
Phase 1: First, you notice that there are water orb generators in the room. You step on the party button, and a vast, black dragon descends upon your party. It begins by hovering in the air, swiping and jabbing its tail at you. Each swipe strongly stuns you, so try to wait out these attacks until the dragon lands to roar at you. The dragon's mouth is its only weak area, and opens up when he roars. Hitting him in the mouth enough will make him enter the second phase.
Phase 2: The dragon stops its constant hovering and roaring and starts swooping at you, trying to bite you as it passes. Striking the dragon in the mouth with sufficient force (e.g., charge attack, hint hint?) will interrupt his attack and cause him to try again. Otherwise, you'll have to tank the damage he'll do to you as you strike back. Doing enough damage will cause him to enter the third phase.
Phase 3: The dragon is grounded now, but still dangerous. Now, it attempts to circle you as it blows fire in your faces. It's still only vulnerable in the mouth, but it only opens to breathe fire, and the breath knocks you back. The only way to get in is to put out his fire with water, which causes him to charge at you with his mouth open and try to bite you. After hitting him in the mouth enough times, phase 4 begins.
Phase 4: The dragon enters multiphase mode. It hovers in the air while jabbing at you with its tail, then lands to blow fire. If you put out the fire, it will charge at you (mouth open) and try to bite you. Successfully hitting it in the mouth enough will kill the dragon and win you the fight. You will be granted 1-5 tokens and every party member will receive a Dragon Scale material.
Bonus:
If you constantly freeze, stun, or tranquilize the dragon without otherwise hurting it, it will turn green and become friendly. You'll still be granted your drops. The dragon responds to emotes, e.g. acts happy when you laugh, releases a tear when you cry, and playfully darts around the room when you express a desire to dance. Turning the dragon friendly is very difficult and time consuming, and you won't get a Dragon Scale material if it lives, since the material is only dropped when the dragon dies.
What do you guys think of this boss fight?
One thing missing is what monster class would it belong to other wise I thing it is a good Idea
