If Experience from Challenges or Penalty for losing a challenge have passed, repeal their effects.

In the rule Yggdrasil, change the text

and the prize, which is an amount of acorns.

to

and the prize, which may contain a positive amount of acorns, a positive amount of experience, a positive statistic modifier that may be temporary or permanent, or some other temporary or permanent positive effect that only directly effects the Einherjar who is attempting the challenge (but it may indirectly effect other things, such as some Special Abilities sway the outcome of a skirmish).

Insert the following text before the sentence that that says “All Challenge Posts are subject to the Allfather’s approval.”

A Challenge Post shall also contain a Penalty. A penalty can contain the following: A negative amount of acorns, a negative amount of experience, a negative statistic modifier that may be temporary or permanent, some other temporary or permanent negative effect that only directly effects the Einherjar who is attempting the challenge (but it may indirectly effect other things, such as some Special Abilities sway the outcome of a skirmish).

Change the text

If the attempt fails, the attempting Einherjar may not again attempt a Challenge Post until the next week.

to

If the attempt fails, the Einherjar suffers the effects of the Penalty stated in the Challenge Post. If the Allfather rolled a 1 or 2 in the DICE10 roll, and the Einherjar failed the attempt, the attempting Einherjar may not again attempt a Challenge Post until the next week

The more free form rewards and penalties can be blocked before they come into effect because no one can pass or fail a Challenge without the Allfather’s intervention, much like the special abilities of the nominated Einherjar.
