Gel

Location
Gel is located in Kalt Island, immediately visible as soon as you enter the location. To get to it, first enter the frozen river, slide left, down, right, up, left, up, right, up, left, up, right, up, left, down, and left. Climb up the ladder and cast Lash on the coiled rope, and you are led to Gel easily for collection.

Description
When Set, it increases base HP by 9, base Attack by 5, and base Agility by 2.

When Gel's battle effect is used, the user deals a Mercury-based attack equal in power to the user's normal physical attack increased by 50%. There is then a chance that the target's Attack rating is lowered by 25%. Note that attack-dropping effects may be stacked to a maximum of -50%.

Ability analysis
Gel is roughly equivalent to the Mercury Djinni Sour for sharing the very strong 1.5x damage multiplier not seen on any other Mercury Djinni. The difference between them in terms of secondary effect is that Sour may lower all of the target's Elemental Resistances by 40 each, while Gel may lower the target's Attack rating. Whether you want your Mercury-based attack to potentially make an enemy easier to defeat with elemental offenses or to potentially lower the physical aspect of damage the enemy outputs with its monster skills and physical attacks is a matter of taste.

Name Origin
A gel is an apparently solid, jelly-like material formed from a colloidal solution.
