Super Defense Potion Certificate

A Super defence potion certificate is a certificate that is obtained by exchanging five super defence potions with Sidney Smith in Yanille. Super defence potion certificates are stackable and each one can be exchanged back for five super defence potions by talking to Sidney Smith.

Because super defence potions are not stackable and you can only trade twelve items per trade screen, they are often exchanged for certificates so that they can be traded easier and faster.
