New Zilean skin?

Doubt it, they're too busy with even more Ahri and Ezreal skins. To be honest I was pretty surprised by the Blood Moon one he got a year or two back.

Zilean does need a skin, but what one would he get? Zilean is a hard champion to make skins for, and understandably so. He's 90% particle effects, so a skin idea would need to be very compelling or fit his character very well, on order for the skin to really seem "new" and "amazing". The Blood Moon one worked, because it brought something new to the table (the eclipse on his Q), and that's probably why that skin was made.

Ideas which could work is Hextech Zilean, Dark Star Zilean, or even a money-themed Zilean skin, but ultimately, the skin team needs to really feel like a skin for Zilean would work, and be up to standard.

However, Zilean probably does have another skin nearing completion, so it's only a matter of time (ba dum tssh).

He's already got a Zilean skins.

Why do you need more Zilean skins other than Groovy Zilean?
