Encumbrance of a Body

[Trollbait]

Thanks for the replies. Very helpful.

The context is transporting a wounded individual on a makeshift stretcher back to his village after being rescued.

Based on the above suggestions, I think I will increase Fatigue by 2 to any failed Travel rolls (made by stretcher bearers) and make them Temporarily Weary until they rest...

And as they are returning to a fight scene in the village...

Just a Loremasterly point of advice: don't overly "tax" them for attempting this, or in the future you will find them not being heroic. They'll just ditch the body or leave them to die or whatever. This is a good place to allow for traits to come into play, too, like Robust, Energetic, Tall, Hardy, or Determined granting auto-successes.

As Rocmistro wrote, don't punish them for heroism. By the same token, saving a comrade in such dire strait is such an inspiring act of heroism that can grant some extra hope to all witnesses ("nothing is lost till you keep fighting..." or such).

I would resolve it this way: you are "tired" while you carry the body. If you hide it in he bushes to fight the enemy, you aren't "tired" (otherwise, in your system, fighting with a mate slung on the shoulder or not got the same malus) :p
If you carry the body for a day or more I'll give you an additional fatigue point for every travel check (in addition to normally failed rolls).
