Having Defense loaded with a shield equipped will make attacks like Meteor, Invitation of Death, Thunder, Fireball, Tail Attack, Stampede, Rain of Thunder, Flames of Hell do 1 Damage. How it works, I don't know. I was going to ask if someone can explain that because according to the Defense page:

“	This skill does not increase Magic Defense nor Magic Protection and therefore Magic and Alchemy attacks' damage is not reduced.	„

Which is clearly not completely true as I've tanked Meteor.
