The following build succeeds by keeping opponents off balance with slams. You can take large groups like the tenpacks on the fortress wall in Cimerora with defensive flight (staying above the fray blasting them landing occasionally to massively area attack them (Photon Seekers and Solar Flare) The other option is go toe-to-Toe with them in Energy-form. You can solo most elite bosses with Energy-form except the mentalist. If you have veteran powers like Nemesis staff and Fist of MU, debuff opponents first with powerblasts/strikes a couple of times to improve your to hit chance. Will need to carry around some blue inspirations until stamina. And always carry some purple inspires. Here is what I did.
1. Glinting eye
2. Gleaming blast
4. Shining Shield: Resist physical damage so you can scrap a bit
6. Radiant strike: good damage and slams
8. Hasten
10. Swift
12. Luminous Detonation: area blast, with slam effects
14. Build-up
16. Healing
18. Incandescent strike: Best single target damage with secondary effects; nice finishing move
20. Stamina
22. Reform Essence
24. Super Speed (SS), the inherent stealth is nice
26. Solar flare: moderate damaging power stomp with slam effects
28. Proton Scatter--Energy spray area attack no knockback
30. Combat jump--immobilize protection
32. Photon Seeker -- good area damage and slam effects--best with enemies gathered
35. Essence boost
38. Energy-form--Great defense to most attacks
41. Dawn Strike-- Extreme Damage Area attack; best used with Energy-form so you aren't totally vulnerable
44. Conserve energy
47. Super Jump--complements SS; but really sets up acrobatics
49. Acrobatics--Hold protection
