So, tavern level in my dungeon. I'll need some bar contests, and the ones in Basic Set feel like they don't have all the drama that I'd like for Dungeon Fantasy. Here is the first.
Like it says.
Fast Version: Quick Contest of ST. Win, lose, or draw and re-roll.
Slow Version: Quick Contest of ST. Each point of victory is worth 10 degrees of arm bend - first person to lose a cumulative 10+ has lost the game. (Why not 9? Assume it takes an extra point to get the arm to initially bend. Plus 10+ is easier.)
I Hate ST Roll Version: If you don't like rolling against ST, simply roll thrust-based damage and compare. Assume both contestants are using All-Out Attack (Strong) and add +2 or +1 per die, whichever is higher. Extra Effort (Mighty Blows) can be used for its usual effect at 1 FP per second; make a HT roll whenever it is used or suffer the usual injury effects from Extra Effort. Whoever rolls more damage bends the arm of the opponent back by 10 degrees per point of damage more than the loser rolled - first person to lose by 10+ cumulatively loses the contest. Injury can occur thanks to HT rolls for extra effort!
(Editing Later: this would use your basic ST, modified by Wrestling, but not by Striking ST - this isn't a blow, it's a slow and steady push. Lifting ST does apply and you can use Trained ST if you use Technical Grappling.)
(Editing Even Later: Note that Mighty Blows is not normally compatible with All-Out Attack; however, this is for DF, and assumes you have the Mighty Blows perk which does allow this combination!)
For extra fun, stare down your opponent - add in The Contest of Wills (Martial Arts, p. 130) right on top of this!
