Hello fellow adventurers!

I have a question that you might help me answer. If a character aids or interferes another characters action, on a 6- the helper marks XP, right?

Now, if the aid was a success and the one taking an action with a +1 gets a total failure (6 or less). Do both characters mark XP or only the one rolling the dice?

This was a question made by a player on my table and I guessed that only the one rolling the dice with +1 would mark XP, but he seem to think otherwise. There is not much info on the web, so… what do you guys think about this?

Thanks on advance!
