Mm. No matter how many times I've never needed swimming in Adventure mode, all it takes is one champion skillfully dodging into a river to make sure I never neglect to take it.
From my experience even with swimming skill, dodge into a pool and you'll drown. By dodging in you fall 1 z level. Any fall causes a temporary stun effect. Being stunned while in 7 deep water means your drowning regardless of swimming skill. And once you start drowning you can't stop, or climb out without the aid of a ramp (which don't exist anywhere but oceans naturally.)
Maybe just a quick 2% per level of swimming skill chance to stop drowning per turn when not stunned paralyzed or unconscious with open space in the z level above. How often do Olympic divers drown because they forgot how to stay above water after their fall?
Would make swim skill actually mean something in adventure mode, and might reduce the dreadfulness of carp if your specially "trained in a wading pool fisherdwarves" had a chance of recovering from diving in to wrestle one to death. Even if they still had to wait for a miner to come dig them a ramp due to pathing.
But that is wandering a bit into suggestions territory.
So anyway, YAY! More reason to actually pay attention to personalities gameplay wise! If you pick a lazy slacker for your military they'll be too lazy to bother training when the commander is away!
And I can just imagine how that crossbow lesson went.
"So I shot the bolt but it went down a little bit before it hit the target so there must be a downdraft in the practice room. We need to tell the miners to fix that. Anyway I couldn't really get the string to go all the way back on the second shot, so I just hooked it on some sliver near the front, and when I fired it the bolt just fell off the crossbow and pierced my third toe left foot. The wind musta really been blowing down really hard. I don't see why it didn't hit the target otherwise. Anyway I think I'm a pro at this now, so I'm gunna go hunting hippo, don't worry about this week's plump helmet harvest, just throw parties and let it rot, I'll be back with oodles of food in a jiffy."
