Summons become available during Sora's second visit to Traverse Town. If you bring rare summon gems to the Fairy Godmother (located in Merlin's Study), she will help Sora learn how to summon various characters to aid him in battle. Other summons are acquired through story events.
Summons are called upon using the Summons option in the Command Menu. Using a summon requires a set amount of MP, and both of your party members must be present and conscious.
You can equip select Keychains and Accessories to Sora to increase your summoning power! To extend the length of time summons are active, equip the Cheer ability to each party member.
Simba is acquired by presenting the Fairy Godmother the Earthshine summon gem (this is received from Leon during Sora's second visit to Traverse Town). When summoned, Simba's Proad Roar attack can be used to damage enemies in a wide area. Hold the button to fill the CHG gauge; the attack can be charged up to five levels, but your maximum charge level will depend on the length of your CHG gauge (you can increase this by equipping a MP-boosting keychain and accessories, and by equipping the Cheer ability).
Proud Roar LV1
Proud Roar LV2
Proud Roar LV3
Proud Roar LV4
Proud Roar LV5
(Max MP x 2) + 26
(Max MP x 2) + 28
(Max MP x 2) + 30 + stuns enemies
(Max MP x 2) + 32 + stuns enemies
(Max MP x 5) + 300(%) (instant-KO lesser enemies)
After charging, release the button to unleash Simba's Proud Roar attack. A fully-charged Proud Roar can instantly clear out waves of Heartless, but there's a caveat: Sora must remain in place while charging the attack, and any damage taken while filling the CHG gauge will interrupt the process, forcing you to start over. For best results, try summoning Simba in the very first moment just as enemies start to spawn. Costs 2 MP.
Simba's Proad Roar attack becomes especially powerful in the late game, when Sora's max MP is 10 or higher (or as low as 7 MP, with three Cheer abilities equipped); this attack can wipe out entire waves of tough Heartless. Check out the tutorial video for more info!
Genie joins the party as a summon after defeating Jafar Genie at the end of the story episode in Agrabah. When summoned, Genie uses a variety of offensive magic spells and bullets to aid Sora in battle. To use Genie's abilities, you must first lock-on to enemies using the button; Genie can place up to ten (10) targets on enemies, and he can target the same enemy more than once so that it is struck with multiple attacks from Genie.
After locking onto targets, activate Showtime: Genie will cast one of six offensive spells/bullets on each target; each attack type is chosen at random. Genie's magic is effective when fighting larger groups of Heartless, but can deal decent damage to some boss enemies as well. Costs 2 MP.
Sora can still move around and attack will Genie is firing spells during his Showtime attack - take advantage of this to deal extra damage to enemies or heal up while Genie keeps enemies occupied!
Genie's Showtime Attacks
When Showtime is used, Genie will attack each of his locked-on targets with one of these six abilities, chosen at random for each target:
A orange/yellow bullet attack that can damage and stun the target enemy (non-bosses).(Max MP * 2) + 14
Bambi is acquired as a summon by giving the Fairy Godmother the Naturespark - this summon gem is awarded to Sora after completing the mini-game in the first Torn Page of the Hundred Acre Wood. When summoned, Bambi will release MP orbs whenever he makes contact with Sora, allowing you to cast magic spells much more freely. You can equip Treasure Magnet to Sora in order to pull in MP orbs from farther away, and you can also equip Jackpot to Sora in order to increase the amount of MP orbs that Bambi drops.
As Sora defeats Heartless, Bambi's CHG gauge fills; when this gauge fills completely (every six enemies defeated), Bambi will drop restoratives and synthesis materials at a higher rate than the enemies that usually drop them. These dropped items increase in quality and rarity each time the CHG gauge is filled completely. Costs 1 MP.
Bambi is great to summon during boss fights where the boss is susceptible to magic, especially Stop and Gravity magic! If you're on the hunt for Shard and Gem synthesis materials, I strongly recommend summoning Bambi for this purpose - check out the table below for more info!
Prize Items Dropped by Bambi
Bambi will drop specific Shard- and Gem-quality synthesis materials items depending on the world in which you summon him. You must defeat at least 12 enemies in a single area for a chance to earn a Shard material, and 18 enemies for a Gem material. This table lists out the individual rooms that hold enough enemies to fill Bambi's CHG gauge at least three times. Bambi will repeatedly yield tier 3 rewards with every six enemies defeated after clearing tier 3.
1 Minimum number of enemies to reach tier 3 only present prior to Kairi's rescue in Hollow Bastion.
2 Minimum number of enemies to reach tier 3 only present during first visit to area. Bambi does not drop synthesis items from respective worlds in the World Terminus portals; only Mythril items will drop here.
3 In order to have enough enemies to obtain a Mythril, you must have the Bouncywild summon other Powerwilds.
Dumbo is acquired as a summon by giving the Fairy Godmother the Watergleam summon gem. This item is found within a chest inside the Mouth area of Monstro; you will need High Jump in order to reach it. When summoned, Sora will ride Dumbo and guide him toward enemies; press the button to ascend and the button to descend.
Splash Power: (Max MP * 2) + 14 (per hit)
Press and hold the button to have Dumbo use his Splash command; this strikes enemies in front of him with a powerful stream of water. Sora will not take damage while Dumbo is summoned, making him incredibly useful in tight situations where you need to avoid taking damage at all cost. Costs 3 MP.
You can spin Dumbo around quickly while using Splash to keep nearby enemies staggered! I find Dumbo especially helpful when attempting to defeat the Gigas Shadow Heartless in Wonderland. Keep in mind that Dumbo's Splash is considered Blizzard damage, so a few ice-affinity Heartless are immune to it.
Tinker Bell is acquired as a summon after sealing the Keyhole in Neverland. When summoned, Tinker Bell will periodically heal the party during combat; each party member will receive a small portion of HP (1 HP for each of Sora's MP units) about every 2 seconds. Both of your other party members will remain for combat when Tinker Bell is summoned.
Tinker Bell will remain active until dismissed from the menu or if Sora falls in battle. If Sora is KO'd, Tinker Bell will prevent a game over and fully restore Sora's HP before leaving. Costs 3 MP.
Tinker Bell is incredibly useful for long and difficult boss fights. I strongly recommend summoning her for any moments where you're having trouble keeping your HP up.
Mushu is acquired as a summon by bringing the Fairy Godmother the Fireglow summon gem; this is obtained after defeating Maleficent Dragon in Hollow Bastion. When summoned, press and hold the button to have Mushu use his Fire Breath attack: he will shoot rapid fireballs at targeted enemies. The fireballs can track locked-on targets, making them particularly effective against airborne enemies. Costs 3 MP.
If Sora is hit by an enemy attack while using the Fire Breath command, Mushu's fireballs will be interrupted; try to keep some distance between Sora and targeted enemies. Sora can run, jump, and dodge roll while Mushu is attacking.
If you are playing on the Proud mode difficulty, you can easily decimate most bosses with Mushu's Fire Breath using a special exploit described as "damage storage" - this requires that you equip EXP Zero, perform a standard air or ground combo finisher, summon Mushu, and use his Fire Breath attack. Check out the tutorial video for more info!
