Trojan Weapon Archive and Weapon Spirits

At level 40 a Trojan talks to the Job Promo Teleporter in the Job Center to enter Dragland. There, Mr. Pride gives the Dragland Trial: kill the Dragon Spirit to finish it and the Weapon Archive opens. What the archive's weapons and skills do is covered in Inspired Trojans.

With the archive open, the NPC Li Xiaoyao inspires Weapon Spirits. Different spirits are inspired in different ways, and Li Xiaoyao inspires one for you for free.

Spirit Casting raises a spirit's level. Higher levels give better Spirit Attributes, and special effects switch on at certain levels. Each upgrade costs Legendary Essence, which drops in Keen Ravine; talk to Cloud Lee in Twin City (323,452) to go there.

When a spirit reaches 3-Star, Spirit Polishing unlocks. A polish adds extra HP, P-Attack and P-Defense on top of the basic Spirit Attributes. Polishing uses a Spirit Stone or a Chaos Jade (better odds of an increase), both from Keen Ravine.

A 3-Star spirit can also show its Guardian Status, with the weapon floating behind your character. You can view it at the Swordmaster in Dragland.
