Titan's Seal Box percentages don't add up to 100%; I'm guessing this is because the Item Box isn't listed as a possibility. Same is true for Akun's, Tera's, and Kanhel ... actually a whole bunch of the Seal Boxes. Not a big deal I guess, can we assume the missing percentage is all a chance for Item Box?
Also the Seal Boxes say things like "11% chance to contain one
Fortification Stone," but they really contain several.
Minor nitpicky stuff, just in case you're bored and actually can do anything about it.
More seriously, would you be able to make it so that the section that lists the possible items contained in a box expands to the necessary size to display all of them, instead of the small scrolling window? That would make it much more convenient to look through them.
