Hello super helpful forum!

I have a question about the int/vit/etc. talismans that are on sale on the EM...

I noticed that the magical sealed talismans always go for more RP than the normal talismans, but I've never had one (and wasn't around during the talisman event unfortunately) so I'm unsure as to what the difference is...

Could someone explain what the difference between the magical/normal talismans are? Thanks so much, I really appreciate it!
