Vine

Vine (アイヴィ Ivy) is a Venus Djinni found throughout the Golden Sun  series. Numerically, it is the fourth of the Venus Djinn introduced in Golden Sun, and is the sixth numbered Venus Djinni in Dark Dawn.

=In Golden Sun and The Lost Age= "Tangle foes to drop agility."

Location
Vine is a Djinni that is randomly encountered in a specific area of the overworld that otherwise appears to be pointless scenery. Thus, it is very often missed by players playing the game the first time without any outside information. The battle with Vine may ensue in place of a random battle in the circular "island" to the immediate northwest of where you exit Lamakan Desert, led to by the upper of two bridges that are immediately visible. It can also appear on the larger island just north of crescent shaped one. Furthermore, it may also appear on the strip of land north of the exit between the mountains and the river.

In The Lost Age, Vine is one of the five Venus Djinn that Isaac's party brings with them when they join Felix's party late in the game, if no Password data transfer has been used. If a player is playing without a reference source, they are likely to miss this Djinni because of how it only appears randomly in battles in a non-conspicuous part of the game world. Therefore, it is possible for a player to transfer data from a Golden Sun file in which Vine was not found, meaning Vine would not be part of Isaac's party near the end of the game. In this situation, if Vine is the only missing Venus Djinni from the original game, then it can be found late in Treasure Isle.

As an opponent
Statistically, Vine has 421 HP, 30 PP, 175 Attack, 45 Defense, 91 Agility, and 10 Luck. Like all other Venus Djinn that are fought, in terms of resistance, it has a Venus Resistance rating of 193, Mercury and Mars Resistance ratings of 100 each, and a Jupiter Resistance rating of 25, and in regards to its abilities it uses its available Venus-based attacks with a Venus power rating of 125.

Vine can use the following battle commands:
 * Gaia: Used 53 out of 256 times, this is a Psynergy spell that causes the ground beneath the enemy to open up and engulf the party in a wide reverse shower of Venus energy and medium-sized boulders, dealing a Venus-based attack with a power rating of 40 and a range of 3. This ability consumes 7 of its user's PP.
 * Mad Growth: Used 47 out of 256 times, this is a Psynergy spell that causes a group of thorny vines to erupt from the ground and through the Adepts for a short time, dealing a Venus-based attack with a power rating of 60 and a range of 3. This ability consumes 10 of its user's PP.
 * Quake Sphere: Used 41 out of 256 times, this is a Psynergy spell that prompts three rectangular sections of ground underneath the party to jolt upward and retract into the ground quickly thrice in succession, bouncing each Adept three times, dealing a Venus-based attack with a power rating of 65 and a range of 7. This ability consumes 15 of its user's PP.
 * Briar: Used 35 out of 256 times, this is a Psynergy spell that causes a series of quite large spiked vines to grow out of the ground quickly to assault the opposition, dealing a Venus-based attack with a power rating of 70 and a range of 3. This ability consumes 11 of its user's PP.
 * Clay Spire: Used 29 out of 256 times, this is a Psynergy spell that causes three thick stalactites to fall out of the sky and shatter onto the party, dealing a Venus-based attack with a power rating of 85 and a range of 3. This ability consumes 13 of its user's PP.
 * Attack: Used 28 out of 256 times, this is this monster's standard physical attack, but for this monster it is counted as a Venus-based attack rather than a non-elemental attack.
 * Flee: Ued 23 out of 256 times, this enemy has the ability to attempt to Flee the battle, thereby ending the battle if successful without rewarding you with the associated EXP, Coins, and the Djinni itself. Since this is a randomly battled overworld Djinni, however, it can be very quickly fought again just by running around in the same area you first fought it in.

When defeated, Vine yields 230 EXP and 277 Coins, and the Vine Djinni is added to your party's Djinn collection. If you fell it with an offensive Jupiter Djinni like Smog, its rewards increase to 299 EXP and 360 Coins.

It is possible to have four Jupiter Djinn in your collection at this point, so having Ivan summon Thor with them will deal over 400 damage to Vine in one blow - practically a one-hit KO.

Description
When Set, it increases base HP by 12, base PP by 4, base Defense by 3, and base Luck by 1.

When Vine's battle effect is used, a group of wriggling green vines briefly sprout out of the ground at the position of the enemy party. All enemies' agility ratings are temporarily lowered down to 50%, the lowest value the Agility rating can be debuffed down to. This is identical to the effect of the Venus Djinni Mud in The Lost Age.

Ability analysis
In various viewpoints, halving all enemies' agility ratings is equivalent to doubling all party members' agility ratings with Djinn like Zephyr. And as a matter of fact, halving the enemy's agility does have one situational advantage over the alternative: because it does not count as a buff to your party, if the enemy is a boss with the Break Psynergy, it cannot negate the agility disadvantage before the normal timer for the effect runs out naturally. Vine works against bosses like Deadbeard, who ordinarily remove all buffs you cast upon yourself with Break but do not have any specific measures to remove negative effects from themselves. So, depending on your party setup and battling approach, Vine can be very useful.

In The Lost Age, when Isaac's party joins Felix's party along with their returning Djinn, Vine's ability makes it a second Mud, a Venus Djinni found in the early-middle of that game with the exact same effect. The two Djinn are usable interchangeably for the same situational purposes.

=In Dark Dawn= "Tangle multiple foes to drop Agility."

The Djinn Guide entry for Vine reads as follows: "This spirit has  influence over seeds and is found in Teppe Ruins. In battle, Vine plants  seeds that grow with amazing speed to hamper foes."

Location
Vine is found late in the Teppe ruins, in the room before the room where Sveta is met. It will run away into tall grass, and will run away from the player through the grass for as long as the player tries to catch it, so the player must walk up a ledge to the left of the room and move an earth pillar up one tile into the grass. With this pillar in place, when the player next chases Vine, it will encounter the pillar and position itself up north in the open, and you can grab it without fighting it.

Description
Like in the previous game, when Set, it increases base HP by 12, base PP by 4, base Defense by 3, and base Luck by 1.

When Vine's battle effect is used, the 3D model of Vine appears and disappears briefly, and a small, yellow-glowing fissure appears under the enemy's feet briefly, and a small collection of green, leafy plants grow out of the fissure and hold for a moment. All enemies' agility ratings are temporarily lowered down to 50%, the lowest  value the Agility rating can be debuffed down to. This is identical to the effect of the Mercury Djinni Foam.

Ability analysis
To cut all enemies' agility ratings in half is more-or-less equivalent to doubling all party members' agility ratings with Djinn like Fleet and Torrent, but with the additional, situational advantage of not being able to be dispelled by the enemy if the enemy has the Break Psynergy. In general, Agility-modifying effects may not be as useful in Dark Dawn as in previous games, though, because with equipment like the Zol Ring, your party is more likely to move before your opponents anyway. This makes Vine one of the less useful Djinn in the game.

=Name Origin= A vine is a type of plant characterized by climbing up trees or other surfaces as they grow. Ivy is a type of vine that often known to climbs up walls of buildings, but is essentially a synonym to a vine. Coincidentally, "Ivy" is the name of a separate Venus Djinni introduced in the English version of Dark Dawn.
