Below is a list of gems and where to currently get them. Phantom Forest - Gem of Tenacity (Life +2500) Lunar Valley - Gem of Fortitude (Defense +150) Aria Lake - Gem of Ferocity (Attack +150) Mirage Ruins - Gem of Healing (Recovery +150) Pagos Coast - Gem of Conviction (Resist +20%) Seabed Caves - Gem of Protection (Defense +20%) Magma Crags - Gem of Life (HP +20%) Star Sanctuary - Gem of Valor (Attack +20%) Golem Dungeon - Gem of Vitality (Recovery +20%) Golem Dungeon - Gem of Ruin (Crit Damage +40%) Golem Dungeon - Gem of Intuition (Crit Rate +20%) The % boost only works on the base stats. It does not give a percent boost of other gem stats. With that said, the percent boost is still almost always better. Gems can only have 4 different "bonus" stats, so if you have a gem that has 4 already, you should know that the bonus stats will only add on to one of the ones already listed. Still a work in progress!
