Torch

Location
Torch is located on a rooftop of Lalivero that is somewhat tricky to reach. You would have to enter the Weapon and Armor shop to the lower right of the town, climb up the ladder to the roof, hop right onto the wall that surrounds the town's upper perimeter, walk the wall counterclockwise until you're on a rooftop on the upper left of town that has one lone pot on it, hop right to the building to the right of that, and climb up the green vine to collect Torch.

Description
When Set, it increases base HP by 9, base Attack by 3, and base Luck by 1.

When Torch's battle effect is used, the screen is briefly lit up with a wavy, oscillating heat effect, and the target is hit by a Mars-based attack equal in power to the user's normal physical attack with an additional 30 damage points added to the result. There is a chance that when the attack hits, only 50% of the target's current Defense rating is applied, sharply increasing Torch's damage.

Ability analysis
In Golden Sun, Torch is not as good a Mars attack Djinni as Scorch because it deals an attack oftentimes not as strong than Scorch but sometimes stronger, but without any other secondary effect. It could only be more valuable than Scorch against an enemy with very high Defense, such as Ice Gargoyles, but even that is a subjective matter.

In The Lost Age, when Isaac's party joins Felix's party along with their returning Djinn, Torch is an identical but weaker version of the Mars Djinni Core, which adds 40 bonus damage. If a Djinni that sometimes ignores half of the target's Defense is valuable in any situation, Core essentially makes Torch obsolete.

Name Origin
A torch is a stick with a flame on the end. They were originally used to find one's way at night or in dark places, but with the invention of lightbulbs (most notably flashlights) torches are now rarely used for their original purpose.
