First and only bossfight

[hagane]

I would like to have about three phases:

1. DPS check: something along the lines of "you either push The Keter to the next phase in X seconds or it unleashes a barely survivable attack"
2. Dance Dance Disintegration: dodge telegraphing/delayed AOE blasts while dishing out damage?
3. that's kinda an open question. I would like to do something along the line of simon says with stagger/burst dynamic, like 'if you do a sequence of actions hinted by boss or environment, the boss drops his invulnerable defence for a limited time, rinse, repeat', but that looks way complicated.

@ForNeVeR @rexim @Akon32 i need your input on this. What can we do without introducing a lot of complexity? We can limit the scope to only one mechanic or even fallback to a simple juggernaut boss that can take and deal a lot of damage.

I'd say that for the first version we want the simplest boss possible, i.e. the "juggernaut" one. As for the complex mechanics — yes, they're interesting, and we'll probably add them to the later versions.

Personally I'd prefer a boss with some interesting non-scripted abilities, e.g. teleport when out of sight and strike from the back.
