Donning armor

[phiwum]

Any notion how long it takes to don armor when caught unawares?

Obviously, it depends on the armor, with plate being damned difficult, but I'm just thinking about what happens when a fight begins with unprepared folks. Is it plausible to don leather or chain before joining the melee? This sort of thing must come up in attacking or defending strongholds, where some people will be off duty and asleep.

For that matter, when camping, do you allow characters to sleep in chain or more uncomfortable armor? I'm leaning to a point of fatigue being likely, as described in the woodsman skill.

Thanks.
