Fel Lotus

Fel Lotus is a herb that can be acquired by herbalists while gathering other herbs.

Source
Fel Lotus does not have any nodes of its own, but has a small chance to be found with any other herb in Outland, similar to the way Swiftthistle is found with Briarthorn, or Eternium Ore is found in any Outland mining node.
