Its in-game description reads "Short sword with a beautifully-patterned blade."
As a short sword, it has the 6-hit combo and good Cyclone and Beast stats, so it's useful against animals.
You can find the Choora in dungeons' chests, it cannot be invented but you'll be able to buy it at G-Weapons in the Gundorada Workshop when the shop itself is restored in the Chapter 5.
It's a medium-tier weapon (Tier 5) : it'll gain 4 Synthesis Points (SP) per level-up.
The Choora can only be built up into the Small Sword when you've got on this sword the following stats : 81 in Attack and 54 in Lightning, Cyclone, Exorcism, Beast and Scale.
Starting stats (When bought or found)Edit
