Challenge Sigil

A Challenge Sigil (トライアルシンボル) is a key item that is found in Kingdom Hearts 358/2 Days. Challenge Sigils are obtained by completing the various challenges in Story Mode, and can be redeemed at the Moogle Shop for various freebies, although they are not used up when redeemed.

The number of sigils obtained from a challenge depends on how well Roxas fulfills the challenge's requirements, with a maximum of three.

Trivia

 * The total number of Challenge Sigils in the game, 255, is reference to the day that Axel told Roxas why the sun sets red. The number is also the decimal equivalent to the maximum two digit number in the hexadecimal system, FFhex, which is why it is used as a max value in many Final Fantasy games.
