Though when you are on the ground, you can put people in leg-locks, so I would assume it would be possible to grapple with your toes if you are prone on the ground.
Not really, I'm afraid. [STANCE] bodyparts don't seem to have any wrestling moves associated with them.
Like I said, if I added [LIMB] to toes, you would be able to. When prone on the ground, you can wrestle with your upper and lower legs, because they have the [LIMB] token.
As feet do not have either [LIMB] or [GRASP] tokens, they cannot be used to wrestle. Though adding [GRASP] to feet would be hilarious
I cant seem to replicate the problem of toes and fingers not being covered by armor. I however dont recall whether or not the ones I use are modded. Heres one:
[BP:TOE1:first toe:STP][CONTYPE:STANCE][DIGIT][SMALL][CATEGORY:TOE]
[DEFAULT_RELSIZE:5]
Whatever this does have, and the bugged ones dont, is likely what fixed the issue. If not the maybe it got fixed, but nobody noticed yet.
I do wish I could get this to work with throats and noses.
Odd, those tokens look right, and I can't seem to recreate it in arena mode. It may just be that the wiki is outdated, it wouldn't be the first time. Though facial features not being protected and body armour protecting almost everything when they have a high enough [UBSTEP] still seem to be bugged.
Edit:
So we could have assless chaps (i.e. do not protect the legs) that are so long they drape over the feet, covering the toes. But all of our shoes and boots are open toe. Very interesting. Dwarven fashion is a cruel mistress.
Body and leg armor can never protect hands, feet and head. It can however protect everything else, including the legs, arms, throat, nose, and possible fingers and toes.
If you want some of those funky assless chaps you have to make very long boots.
To add on to the "ass-less chaps" conundrum, the reason they must be defined as shoes is because of the way pants are worn. Pants and other lower body apparel are actually attached to the lower torso, which is an area that covers the bottom of the ribcage to the bottom of the hips, and from there is where the upper legs start, which is why it is possible for legless dwarves to still wear pants. Therefore, an article of leg clothing with an [LBSTEP] of 0, such as the short skirt, is quite literally a belt.
Though I see nothing wrong with modding in +Steel Championship Belts+ for your wrestlers.
