The rules say that i must add the Stength of all participating characters to see who wins a challenge, but, what happens if any of my characters have a negative strength? (due to attachments or abilities or any other source).

Do these characters reduce my total Strength in that challenge?. After all... if i add a negative that's a minus...

No.

Character strength just bottoms out at zero. It can't go into minus figures.

As such, those characters will just add nothing to your strength in the challenge, they won't actively reduce it.

Hopefully that's help ful (and no doubt one of the resident experts will correct me if I'm wrong).

That's defeinitely in the rules (p.23 Lasting Effects). Keep in mind that you ave to completly recalculate everytime the situation changes.

I. e. if you have a +2 and -3 attachment on a character that has 2 Strength, you end up at 0 (actually -1 but there are no negatives in play). If you now play a card that gives that character +1 on strength he is still at zero (2 +2 -3 +1 =0). So its not like the modifier is added to the 0 Strength it was played on, but recalculated. ups does anyone understand what I've written? Even I don't .

But the overall information is correct. When you calculate a character's STR, if the result is a negative number, you round it to 0. A character's effective STR can never be less than 0. But if you need to calculate that character's STR again, you start from the very beginning, not from the currently "effective" STR of 0.

If you put Poison Wine (-2 STR) on a 1 STR character, it's calculated STR is -1, but you treat it as 0.

If you then use Heart of the Kingdom to give it +1 STR, you start the calculation over (getting an answer of 0) rather than from the effective STR of 0 (which would have given an answer of 1).
