Help with beginner Ast

[Rongway]

Yes, Lucid Dreaming also affects Enmity which is aggro. In this case it reduces enmity, I wanna say its halves current, or did it take the reduces generated from the original AST skill for it.

It's drops your enmity down to ever so slightly above half.
Unimportant in practice, it drops you to 50%, but then adds a small fixed amount of enmity like any action that grants a self buff.

The deleted pre-Stormblood ability Luminiferous Aether was an enmity suppressor instead.
