Tinder

Tinder (フェニキ Phoenic) is a Mars Djinni found in Golden Sun:  The Lost Age and Golden Sun: Dark Dawn.

Tinder is the eighth Mars Djinni in Golden Sun: The Lost Age. The separate Djinn list viewable with the Select button from the status screen lists Tinder and all other Mars Djinn introduced in The Lost Age before the seven Mars Djinn from the original Golden Sun, most likely because all the Djinn from the original game can be gotten all at once late in The Lost Age. However, the original Djinn are ordered before all of the Djinn introduced in The Lost Age in the Djinn inventory screen while they are allocated to characters. By this order, Tinder is the fifteenth Mars Djinni in the GBA series, rather than the eighth.

Tinder is the fourteenth Mars Djinni in Golden Sun: Dark Dawn.

Basic description
When Set, Tinder increases base HP by 12 and base Psynergy Points by 5.

When Tinder is unleashed in battle, the selected Downed Adept has a 100% chance to be revived, and their HP restored to 100% of their maximum HP.

In The Lost Age, Tinder's unleash animation visually resembles the user summoning the red image of a Mars Djinni floating above the targeted ally and leaving up off the screen, and the targeted Adept is briefly surrounded in a slowly rotating, expanding set of vertical red lines arranged as a cylinder, while detailed red images of bird pinions flutter down over the target. In Dark Dawn, the user summons the 3D model of Tinder above the target, and then a circular orange field forms under the target while orange bird pinions flutter down from above, and both the pinions and Tinder disappear into the field. Then the field erupts through the user in a vertical orange pillar-like beam comprised of a collection of thin orange lines arranged around a central pillar of energy like a cylinder.

Locations
Golden Sun: The Lost Age: Tinder is located in Hesperia Settlement in the far western region of Hesperia. Cast Growth on the plant to the left, then at the top of the area where there is a wooden crate, push it off the left hole in the fence below. (Note that it is possible to push the crate off the right hole so that it drops onto Tinder and traps it, causing the box to shake similar to what can  happen in Kibombo Mountains; you'll have to leave and reenter so that the puzzle resets itself if that happens, though.) From there, press the box right so that it falls further down, then use Move while standing below it to move it one step further right. You are now able to hop onto the top of the box and reach the series of wall ladders that connects to Tinder's ledge, as well as the cave on the opposite side containing a chest with 166 coins.

Golden Sun: Dark Dawn: Tinder is immediately accessible when the town of Tonfon is first entered, meaning this Djinni can be found as soon as you start out in the Great Eastern Sea with the Sailing Ship. To reach it on its spot on the roof of the item shop, go to the main town area's northwest corner, hop onto the bluish tiled roof below, and walk along the screen's west perimeter and climb down a tree. Right of this tree is a lone wooden crate, and when you hop onto it, you will be facing a sleeping man in front of a ferry on the wooden dock. Cast the Slap Psynergy to wake him up and prompt him to sail the ferry north. Retrace your steps north along the blue-tiled roof, and the ferry's new position lets you hop right across it to get to the roof of the item shop on which Tinder waits.

Analysis
General: Tinder is the one best Djinni out of all Djinn that attempt to revive a Downed Adept. All other reviving Djinn have only a chance to work, and they only revive the Adept to a portion of their maximum HP if they do. Tinder, on the other hand, has a 100% chance to work, and it fully revives the targeted Adept, making it identical to the Revive Psynergy and Water of Life item without any strings attached. Tinder is best on an Adept in a class that doesn't have Revive, particularly if the Adept doesn't have the party's Waters of Life. If the Adept in question is in his or her mono-elemental class series, this is best on the Adept that has less attack, and is all the more good if that Adept has an odd number of Djinn set, so that the Adept's class doesn't lower once Tinder is unleashed.

By game
Golden Sun: The Lost Age: Tinder far obsoletes the only reviving Djinni the party has up until they first enter the Great Western Sea, Spark, as well as the two reviving Djinn Isaac's party may bring with them when they join Felix's party later, Dew and especially Quartz. The only reviving Djinni that can possibly have some use of its own is Balm, which when used by the lone surviving Adept of a party row where the other three Adepts are all downed, gives all three of the other Adepts a 60% chance to be revived to 60%. But this is conceptually rare and unreliable in practice.

Golden Sun: Dark Dawn: Tinder has the same role as in the last game, far obsoleting all of the other Djinn that attempt to revive Downed party members: the "50% Djinni" Jolt, the "60% Djinn" Cinder and Teardrop, and the "80% Djinni" Glow. Since the final boss and optional endgame bosses have far more capacity to knock out your party than anything else in the game, Tinder can be used to both revive a Downed Adept and partially set up for a Mars Summon.

Tinder will be strongly discouraged from use at that point at the end of the game and the postgame beyond that, however; The Tua Warriors that are randomly fought at Apollo Sanctum before the final boss guarantee dropping a Water of Life every time they are defeated in a battle, and there is no limit to how many Waters of Life you can amass, and amass easily. Should enough Tua Warriors be fought that every Adept has their own collection of Waters of Life to use in the final battle and the postgame, none of the lesser reviving Djinn should ever be used. Tinder, for being a Djinni that emulates the effect of a Water of Life, may still have some possible use because it can be used for the dual-purpose of both revival and putting a Djinni on standby for a summon.

Name Origin
Tinder is easily combustible material used to ignite fires. Phoenic comes from Phoenix, a mythological bird known for it's ability to be reborn from it's own ashes.
