Jade Mech CJ-1

Jade Mech CJ-1 is the profession mechanic of the mechanist, engineer's elite specialization. It is a combat mech summon from the Canthan line of Jade Mech automated assistants. Jade Mech CJ-1 is controlled similarly to ranger's pets, while its skills and attributes can be customized by mechanist's traits.

Mechanics

General

Mechanist's skill bar of the Jade Mech CJ-1, displaying controls, Mech Command skills, health status, and Recall Mech skill

Jade Mech CJ-1 is always present by default and can be stowed by using   Recall Mech skill. The skill is replaced by   Crash Down which respawns the mech if it was defeated or recalled. The mech can be renamed by Right-Clicking Recall Mech or Crash Down.

The Jade Mech has its own attributes, which can be viewed by mouse hovering over its healthbar and modified by changing mechanist's equipment and certain traits. It can also be damaged or killed by enemies; the health pool replenishes when out of combat. The mech is immune to control effects in PvE game mode but is not in Structured PvP or World versus World modes. If the mech was defeated or recalled while at low health, the recharge of the   Crash Down is increased proportionally to missing health.

Controls

Similarly to ranger's pets, Jade Mech CJ-1 can be set either to Guard or Avoid Combat mode by mouse-clicking the toggle button on the skill bar or by pressing "Ranger Pet Combat Toggle" keybind (unassigned by default in Control Options → Miscellaneous).

The mech on "Avoid Combat" behavior will never attack enemies until specifically commanded to do so with Attack My Target (default keybind F6 ). Depending on the auto-attack type determined by the traits, the mech will either move in melee to perform the attack or will stay ranged.

If the Jade Mech is set to "Guard", it will automatically join the mechanist in attacking its target or will defend the owner if they were attacked. The mech stops attacking and returns to the mechanist if the command Return to Me was used ( F7 ). The always selected  Mechanical Genius trait provides special benefits if the mech is in close range to its owner.

Active combat skills

Mech Command skills replace engineer's tool belt abilities and are determined by the currently selected mechanist's traits. Mech Command skills can be set to auto-attack and will be used in combat automatically whenever they are recharged (only in "Guard" mode). Two additional active abilities of Jade Mech CJ-1 are triggered by using mechanist's mace skill 3,   Rocket Fist Prototype, and their elite skill,   Overclock Signet.

Skillbar

Default keybind	Command
F1	Selected Mech Command skill 1 — commands the mech to use their first skill on the current target.
F2	Selected Mech Command skill 2 — commands the mech to use their second skill on the current target.
F3	Selected Mech Command skill 3 — commands the mech to use their third skill on the current target.
F4	Recall Mech — recall your mech for repairs. The cooldown of Crash Down is increased by a percentage of your mech's depleted health.   Crash Down — summon your Jade Mech at the target area. Foes in the area are damaged and launched.
F6	Attack My Target — commands the mech to attack the currently selected target.
F7	Return to Me — commands the mech to stop attacking and move close to the owner.
	Guard — instructs the mech to automatically assist the mechanist in combat or to defend the owner if they were attacked. Avoid Combat — instructs the mech to avoid combat; the mech won't defend the engineer from foes that attack them.
