Whenever you start implementing some of the tougher bosses, here is one idea for an Overlord tier boss (or whatever the highest rank of boss is)
Anyone play Final Fantasy XII? Anyone remember Yiazmat? Yea, basically the idea is that.
Something like, even if you are 10 levels above this new boss, it still would take you like 30 minutes at best to take out. (You would be able to leave the room, heal up, and come back later)
Even if you are 10 levels above it, it could still kill you in 8-10 hits.
It would be able to inflict debuffs (burn and/or freeze and/or other debuffs to come along)
It would be immune to death touch or any other instant incapacitation spells.
It would be able to self regen after 20 or more seconds of not taking damage (though at a VERY slow rate compared to its total HP, though with that kind of total HP, that still would be quite a bit)
It would give ludicrous EXP on death (even by overlord standards)
Yea, this would have to be a very rare encounter, even by overlord standards, but I think it would be epic.
Any ideas for less "insane" high level bosses?
