Before heading off to battle, pilots of each country can put the fruits of their training towards acquiring new abilities that expand their combat potential here. Even the best veterans regularly make trips to these training facilities in order to stay in top shape.
A knight can bring up to four artes that they've mastered into battle. They can also wear multiple talismans to bolster their capabilities. Most limit themselves to three since the talismans themselves consume precious magic, but those who put in the time and effort to bolster their reserves are able to carry far more than that.
At the cavalry workship, pilots can switch out their weapons, as well as purchase new ones and perform upgrades to make them stronger and more capable than ever. Newly developed weapons are constantly rolled out, making it worthwhile to regularly visit the workshop. Jewels can also be earned as special rewards for defeating demons that routinely appear throughout G Bound.
Suffice it to say, it's important for pilots to always be prepared and keep their equipment and machinery maintained so that they can rise to any challenge that may confront them at a moment's notice.
