In a recent game, one of our fellow 'gravers insisted that Resisting a spell with a will roll could be empowered, but passing a will roll versus a spell effect could not. The Beauty spell clearly states that when you're attacking a target with beauty, you PASS a will roll. The section of the rule book on resisting spells states that many spells allow a target to RESIST the spell with a will roll.
We didn't want to argue, so we didn't allow empowering of the Beauty will roll, but it seems the spirit of the rules would be that you're resisting the effects of Beauty, so you should be able to empower. Which is right?
