Recenly, i got a message that a salt humanoid appeared in caverns. I never do any entrance, when i find caverns, so it could wander down there forever. But i actually was very bored, and the appearance of such mighty beast made me excited. So i gathered 6 my best soldiers (all champions etc) and stationed them, while a miner made a passway for monster to pass thorugh. I've read, that inorganic beasts are real threat, as they can't be killed by any dwarven weapon but the decapitation by axe or other slashing weapon. So, i was looking for really intense battle. And what did i get? My militia commander with her steel spear made couple thrusts and that forgotten beast (!!!) died falling apart and leaving after him 2 salt units. I was so surprised, that i even reload that save. Same with my maceman. And same with my other spearman. That FORGOTTEN BEAST was WEAKER the a mere GOBLIN AMBUSHER. WTF??
It seems like that the size is what matters. It wasn't enourmours - most probably, just around human size. But that's not how i imagined FB - enourmous beasts with poison breath capable of tossing any dwarf with ease and fast like hell. Even the first one i got was a weakling too. It was huge, had some noxious breath (or whatever it was) and it was flying, but still fell down after 20 pages of fight (that might be decent for goblin, but not rly suits the description of FB)
P.S. The first FB i found was much tougher. Though it couldn't even leave scratch on any of mentioned higher 6 champions, the battle lasted for 20+ pages and eventually it made some destructions.
Is it me unlucky, or there is somewhere bug? I mean, FB must be really tough and hard to kill.
