If I declare a P challenge against my opponent. Attacker's STR is 1. Then, the STR of opponent's defender is 5.

When resolved, I play the "True Power".

Does It be defined "I win the challenge by 4 STR."?

Tthanks.

I think that "winning a challenge by 4 or more STR" means that:

(total STR of the winner) minus (total STR of the loser) must be equal or greater to 4.

in this case:

1 - 5 = - 4

which is less than +4

So, in this case, "Winning by 4 or more STR" is a false statement.

Correct. In the situation described in the example, the attacher wins by -4 STR. (You could not trigger Flame-Pitch Tower.)

got it

thanks
