[1.2.339] Lionheart Castle?

10% exp isn't worth more than 50k. i've got a bridge to sell anyone who pays that.

You need half as much EXP post-BB so it's like 20%, on top of 2x card, 1.5x HS and 1.2x family (plus 2x internet cafe, 1.1 monster card and any events), so it's more like 72% exp counting just the first three (126% if you count all six).
