i suggest just sticking a post-it note on your monitor with "plutonium has no effect" written on it. plutonium does nothing right now unless its used for the center of the sheild, in which case it makes the effect of the other metal stronger. plutonium will just block a monster like any other sheild if it is used as the base. if you see someone walking around with a big, purple sheild, they have just wasted their money. it has no special power as the base of a sheild right now, despite whatever rumours you hear from other people. I think you might just be pretending to be stupid to try to annoy us. if not, i truly feel sorry for you.
