Looks like the next level of Relic is about to come..

I always thought, as someone probably already brought up, that Zenith can mean the very highest point. Although if memory serves, it can also just mean up or above.

But if they can transform and maybe...get a different model then I'm all for it.
It keeps the relic system relevant. I think its a good option to compare side by side with something like a primal weapon.

By definition, Zenith means the highest point, or culmination of something. Also, taking into consideration that they renamed augmented relics from +1 to Zenith not too long ago, this coming update was done with that naming convention in mind. Therefore, I'm going with what some people are saying here: ex: Curtana > Curtana Zenith > Excalibur > Excalibur Zenith. This alone should last until the first expansion.
