Eidolon (Dimensions II)/Free-to-play

Summons are creatures that player's can call forth in Final Fantasy Legends: Toki no Suishō. Similar to the Espers of Final Fantasy VI, summons play a pivotal role in the game's story and as well as influencing the game's core gameplay. Summons are obtained in the form of items called as Phantom Stones and can be equipped by party members. Equipping a Phantom Stone allows the player to equip abilities, increase stats by upgrading summon Phantom Stones, and summon the creature in battle.

Obtaining Phantom Stones
Phantom Stones can be obtained from completing certain parts of the storyline and quests. Players also have the opportunity to obtain high-level summons by exchanging Space-Time stone that may be obtained as quest rewards or through a cash purchase. In addition, certain game events rewards players with rare summons, Space-Time stones, weapons and rings.

Equipping Phantom Stones
Players can only equip four Phantom Stones to a single character and may not equip a stone if the character's limit is not enough. All characters have an ability to decrease MP costs of certain Phantom Stone when placed in first slot.

Leveling Phantom Stones
Summons can be leveled and can be upgraded in rank after their Phantom Stone has reached the max level. Upgrading Phantom Stones require the player to have the summon fully leveled on its current rank and certain tails obtained in dungeons. However, once a summon's Phantom Stone is upgraded in rank, they revert to level 1 again and must be leveled up once more.

When the inventory is full, the player may choose to use up the remaining tails for upgrade or trade the items for CP. Normal element tails, weapons, rings are only traded for 1 CP, while element stones and rank stars could be traded for 5 CP. If the player recycles a Phantom Stone, they will receive 0 CP.
 * In some events, some phantom stones can only increase in rank by collecting the correct materials only present in the event.

Phantom Stone Limit Break
There are additional stats beside each phantom stone that is currently equipped. These stats may be increased beyond the stone's limit by using special potions.

Phantom Stone Slot Limit
If the cost is higher than usual, it normally means the potential stats are higher, and vice versa. Phantom cost max limit may be increased by 1 per level up. Normally the Cost limit is almost equal to the player's current level.
