The Retch DoT can cause kills to be lost, preventing exp, flask charges, iiq/iir

The Retch's % of Life Leech applies to Enemies as Chaos Damage can be applied by objects like totems and mirages, which can then die/expire/be replaced, leaving their DoT orphaned on enemies.

Because this DoT doesn't have the 'always credits player with kills' bug/bugfix that most other DoT has, monsters are able to die without crediting the player.

No exp.
No flask charges.
Drops an item despite 100% reduced quantity.
