Please restore Stalking Pustule (Previously Duskblight exclusive skill)

I was extremely fond of the unique skill Stalking Pustule in that it was one of the very few skills that triggered on death of enemies and created a very fun unique playstyle. It was also one of the few chaos skills in game and the ONLY chaos corpse detonation skill.

Please either introduce Stalking Pustule as a new skill all its own (perhaps even the first trigger gem that only occurs on death) or Re-introduce it with a new / existing unique item.
