Rainbow Key
Ticket used in The Rift to obtain Cores.

The Rainbow Key is one of the high-end currency Items in Mobius Final Fantasy.

Rainbow Keys are used to purchase "Core" materials from The Rift regions. These are used to unlock advanced Areas that can reward Extreme Sicarius cards, which have abilities equal in power to a Supreme Card, but without being at the mercy of the rare card summon rate.

Acquisition[]

Rainbow Keys are used as a high-end reward for veteran players. They currently are obtained in only two ways:

Ranked events[]

Ranked "Tower" events offer at least one Icon Rainbow Key Rainbow Key for every player who reaches the top 2,000 scores. Doing so usually requires a player to complete at least 3-5 full Phantasmic Loops. (Boss Kills > ~50)

Tower Rank Keys
1 – 50 10
51 – 100 6
101 – 500 3
501 – 1000 2
1001 – 2000 1
