Shadow Word: Death Indicator

Know when Shadow Word: Death will finish your target.

When your highest rank of Shadow Word: Death will kill your target, a soft purple glow hugs its health and power bars and its portrait turns into the Shadow Word: Death icon with a pulsing halo. It works with EllesmereUI, ElvUI, Shadowed Unit Frames and Blizzard's target frame without any setup.

Commands

Tuning the estimate

The damage comes from the spell's tooltip, and the low end of its range is used by default, so the glow never shows on a target that would survive. If your tooltip leaves out spell power or Shadowform, compare /swd debug with your real hits and adjust:

How detection works

Forever hides the target's health from addons in combat, so the addon can't compare it with Shadow Word: Death's damage itself. A status bar still accepts the hidden value, so the addon feeds an invisible, very long bar with the target's health as its maximum and the spell's damage as its value. The bar only fills to its end when the hit is lethal, and the glow sits at the end of the fill inside a clipped window, so it's only on screen when Shadow Word: Death will kill.
