Predicts the healing that your next Death Strike will do, and visualizes it by overlaying a small bar texture on your health frame. The aura automatically finds and attaches to your health bar.
Q: I cannot see the aura, or it does not automatically attach to my health bar.
A: Currently SUF, PitBull, ZPerl, ElvUI, TukUI, and Blizzard frames are supported for this. If you're not using one of these, go inside the display tab -> position settings -> anchored to -> select frame. You can now manually select your health bar. If this still doesn't achieve the desired result, untick "automatically anchor to health" under custom options and manually place/resize the aura.
Q: How do I change the texture/color of the little green bar?
A: Under "spark settings" in the display tab.
