Interesting side note: the cave system is actually very complex, sometimes noteworthy creatures DO go in caves (and if they were in the cave when they kill you, they almost always stay there, prehaps that explains it) i also did some testing and discovered: skeletal titans are possible ( though noone mentions they're undead until its too late and you're on the ass end of an ass kicking ), inside were SKELETAL TROLLS ( many of them ) i got killed by one on purpose, and indeed he became a noteworthy creature (and i was even tasked with killing him, heheh, going on a quest to kill someone who killed me
) creepily, that skeletal titan was roughly as bad ass as the alligator...I recorded it and WILL get round to posting it. he pwned my dwarves
. ( though the hammer dwarf did put a DAMN good fight up considering )
Edit: I have also developed a theroy: The more kills a creature gets, the tougher it becomes, i'm not sure if its a bug, or if its a part of the game. But what i do know is, its a bit like the "camel god" post on the forums (that one though made Conepirni look like a wuss) i assume that this alligator was quite the rarity, and should he have had his vision, maybe, the fight could of ended differently. One thing is true though: Noteworthy creatures are DEFINITELY more powerful than ordinary versions of thier type (by quite a bit). I met a cyclops who had four noteworthy kills, and he was, quite literally. Unbeatable in adventure mode. If kills DOES affect the creatures power, then indeed, one could make a dungeon of super creatures and challenge himself to take them head on.
Also, when i said he was roughly as bad ass as Conepirni, i meant as in: he was pretty much that hard to kill, and hit that hard, not as fast though (he was blind)
