Ghost pendant should work specially for moragen (we're the only faction without two different special hero-equips. Split hero equips don't count) And then ghost pendant from ethereal to ghost. I like these ideas
I already have changed Moragen with your suggestions, I hope you like it (actually, after your your sayings, ZH on her seems pointless, I see no reason to pick it over Battle hymn (on this Moragen)): I would love to see siren song to 4 range and deafening aura to 4 range too
