Since this skill is pretty unreliable, and often fails to cast regardless of corpses, I’d like to see a QoL update for it. Here is what I propose: Make it target an enemy instead of a corpse, creating a tether between you and that enemy (visually similar to Guard or Soul Tether) as well as an AoE centered on the enemy. Give it a Stamina or Magicka cost (depending on morph choice), but make it free to cast if there is a corpse present within the AoE. This way we could aim at the enemy, and not have to do the clunky corpse targeting (which ends up hitting the wrong corpse or no corpse more often than not), and worst case we end up spending resources if something happens where the corpse disappears.
I also like the idea of an AoE DoT centered around an enemy player, because unlike corpses it could move, just not very controllably. It would be fun in PvP, forcing groups to step away from their tethered ally. Also would be nice in pug dungeons, and AoE that follows enemies even if the tank runs around kiting.
