Catarina Aura Effect

Greetings,

Can we have Catarina Forsaken Master Aura Effect? I really like it and it would fit nicely with Summoner Type Witch.

The closest I could find was the Soul Nexus Clarity for the Clarity Aura Skill Gem, but it's Blue.
It would be great if the effect was available to players, or at least let us choose between the colours of the Soul Nexus, from Blue to the Necrotic or Ghostflame one.

Catarina's aura is very similar to the one granted by Dying Breath, if not identical.

I didn't know that item, thanks, I'll check it out.
