Flint

Location
It is automatically acquired once you leave Vale and enter the overworld for the first time, where a cutscene has Flint talk to you and give a tutorial on how to use Djinn. It is nearly identical to Venus Djinni Echo.

Description
When Set, it increases base HP by 8, base PP by 4, and base Attack by 3.

When used, Flint attacks an enemy with Venus power 160% of the user’s attack power.

Analysis
In the first game, Flint is the only Venus Djinni that multiplies attack rather than adding a flat number to it. While theoretically this means Flint does less damage than other attack Djinn, the next damaging Venus Djinni, Sap, is the fifth one in the game, meaning Flint will still see quite a lot of use. And of course, by late game, Flint's damage will surpass other Venus Djinn, though it does lack a secondary feature compared to Sap and Bane.

In the second game, by the time you acquire Flint, you would already have a more powerful Venus Djinn, Geode, available. However, it is still likely to be more powerful than anything else (tying only with Echo).

Name Origin
Flint is a type of stone normally used to make arrowheads and other weapons.
