Rain of Oil shard does not work. (Windows)
Rain of Oil does not apply oil to enemies in any circumstance.
To make sure that this wasn't caused by interactions with other mods or equipment, I removed all equipment except a weak medallion with only the Rain of Oil (20/20) shard in it and here is a .gif of the result in a campaign tier map:
As you can see, the enemies hit by the Skeleton Archer's Direct Command are not oiled nor slowed.
Rain of Oil also (and more irritatingly) does not allow damaging of controlled burn waves, as can be seen in the following .gif:
I've had a second player with the shard also test this, and it does not work for them either.
Repro Chance: 100%
Steps for Bug Repro:
Equip the shard, use the direct command ability.Expected Results: Enemies are neither oiled nor slowed.
