Although this build uses the Auraborean race,
it works well enough with a human,
& should be a good build for unlocking the Auraborean race.

Get Recovery early if you lose a body part.

If you're having trouble with survivability (for example on The Obsidian Bulwark), swap Treasure Hunter out for Stargazer just to get the +100% Barrier Amount.

Primary Attacks (attacks with your chosen weapon, for example Hammer of Sol) generate Energy (blue bar under the players health bar).
Power abilities will trigger when you have full Energy.
Energy is gained not on attack, but on enemy hit,
investing in the following stats will therefore increase the rate at which you generate Energy, & thereby how often you activate your power abilities:

• Attack Speed
  
• Instant Attack Chance
  
• Projectile Amount
  
• Projectile Split Chance
  
• Projectile Pierce
  
• Double Shot Chance

Focusing on Energy generation in this manner is crucial in order for this build to work properly.
