There are 2 guys that play Cards if you pay gil and they reward you with Items if you Win. There are one in 5th Floor and one in 11th floor and here is the items that they give: 5th Floor Card Player: - Potion - Eye Drops - Remedy - Gysahl Greens - Flare Stone - Mega-Phoenix - Phoenix Pinion - Luck Up (One Time only ) 11th Floor: - Potion - Eye Drops - Remedy - Hi-Potion+ - Holy Stone - Mega-Potion - Rosetta Stone - HP Up (One Time only) So you can get As many Rosetta Stones as you have patiences for, they are pretty Rare though I just got my second one i'm going for 3 ^^
