Notes/How to use: Starlord has some quick little powerful attacks along with one nerf attack. Always keep Pulse Compression and Pulse Dilation alternating each time they cool down. Nice quick spurts of big damage, plus slowing your opponent. When fighting multiple enemies, High Energy Arc can be used against them all at once and even healing you if you had Pulse Compression activated. Energy Arc will remained unused unless you happen to be farming class points/exp/reputation in a room with many monsters. It's a relatively strong attack that gets the job done quickly against weaker monsters.
Class: Fighter / Thief
Helm: Fighter / Thief
Cape: Fighter / Thief
Weapon: Fighter / Thief / Lucky
Notes/How to use: Thanks to its high base stat of dexterity and its passive skill that adds 15% more dexterity, the thief enhancements work well here. Like before, keep Pulse Compression going every time it cools down but this time alternate it with Pulse Dilation and High Energy Arc. I wouldn't recommend using this strategy in a farming zone, as the best for that is the offensive strategy.
