Crystalline

The Crystalline is an item found in Super Mario RPG: Legend of the Seven Stars. It can only be purchased at the "Frog Coin" emporium at Tadpole Pond for five Frog Coins. Using one reduces all damage taken by 50% for all party members, much like the effect from Geno Boost or a DEF UP Flower would have on 1 party member.
