Description: These droids are made to be used against skilled Lightsaber duelists in an attempt to cater to those that wish to hone their Lightsaber dueling even further. It's advanced sensors, heightened reflex suites and advanced servomotors allow it to keep up with even force assisted Lightsaber maneuvers and even block blaster bolts to a degree of an initiate in Shien but not against more than three opponents, even with the two Zuguruk Tyûk sabers impeded within it's forearms (Show in the picture).
It's advanced servomotors allow the droid to move very fast as well as jump almost to the point of Force users. Even despite these features it has several severe weaknesses. Firstly it is very vulnerable to the force, Intended as a training droid it is only capable of being programmed with two full lightsaber form and the beginning stages of another form as well. If it is using one form and another form is employed against it, it will have to take a defensive stance while it analyzes the opponents moves to comply within the forms it employs for use against the opponent.
Even though it has a strong personal shield integrated into it's chassis the shield can only take two or three strong Ligthsaber hits will bring it down and it will have to reset, which takes 10 minutes and then recycle which will take another 2 minutes to complete. This is also taken as a win in training situations against it and combatants are encouraged to stop their training session at that time.
Simple voice commands order the droid and it can also speak back.
