Cid is a Common Cost Medal in Kingdom Hearts Unchained χ / Union χ.
Cid, when fused with a 6★ Medal, reduces its deck cost by 1. A Medal can have its cost reduced a maximum of 20 times, previously 10 times prior to version 2.0.0.[1]
Five Cid Medals can be melded together to create a Cid 5 Medal, which will reduce a 6★ Medal's cost by 5. Two Cid 5 Medals can be melded into a Cid 10 Medal, which will reduce a 6★ Medal's cost by 10. These 'stack' Medals were introduced on March 17, 2016 in the Japanese version,[2] and April 22, 2016 in the English version,[3] as a space-saving measure.
You can obtain Cid Medals by proceeding through the Coliseum Quests, through certain events, in certain Avatar Boards, and as a bonus Medal in Rare Draws during certain promotions. Up to three Cid Medals are also available every day in the Daily Cid Medal Challenge series of permanent Special Quests, which was available only as a series of VIP Quests prior to April 20, 2017 in the English version.[4]
You can also obtain Cid Medals by beating a level 5+ Trident Tail Ω.
