Quick correction to Zabimaru, He's right about Resist Charm, it simply lowers the duration of Charm Spells/JA.
However, Resist Sleep/Silence/etc all have a small chance of "100% Resist" on their spells. Which is where the "Resist! Blahblah Resists ____" comes from.
@Chronos Resist Charm doesn't help you resist Charm, it just makes it so the effect lasts less time once you're charmed. It's the same with Resist Sleep, Silence, etc...
