Jokers

These Special Sidians have the purpose to increase the experiece of a Sidian, and/or increase the Sidian's Fusion Levels. Within them we have:

• Color/Elemental Jokers

These Special Sidians can be used, by fusion, to upgrade the Fusion Level only from a RARE+ Sidian by 1 and give a few experience. They ONLY can be fused with a matching element Sidian (ex.: Hot Joker, being Flame-Type, only can be fused with a RARE+ Flame-Type sidian). 

This is helpful because reduce the need of find lots of copies of a Sidian to increase the Fusion Levels. When the maximum fusion level is reached, fusing a Joker won't have any effect but give the few experience, if the maximum level hasn't been reached.

• EXP. Jokers

These Special Sidians can be used, by fusion, to give a certain amount of experience to ANY Sidian to level them up. The higher the rarity/class of the Joker, the higher amount of exp. she will give.

This is helpful because reduce the need of send several times a sidian to explore to the Gate, or doing too many battles. When the maximum level is reached, fusing a Joker won't have any effect.

The common place to find them is through the Altar of Time, as rewards in some Events and from Ether Summons.
