Bullets Don't Work

Jon...

When someone's main mode of attack won't have any effect on their current enemy, forcing them to find a way around this new problem. But they shouldn't worry — they're probably the good guy, so They'll Figure It Out. While they're fighting (or at least trying to fight) the enemy, the person will have to look out for any giveaways of a Weak Spot they can exploit, like how their foe suspiciously avoids water or light as the two duel. When they finally finds out what the Weak Spot is, they take advantage of it and quickly win the battle.
