It's a bit troublesome that Alexstrasza's jewelry has pink gems, yet everything designed around the Red Dragonflight for evokers has red ones. I used the purple gems on these Venthyr pieces to try to evoke (ha) the vibe on the visage, but the staff and some red-gemmed customizations were too good to pass up. It's impossible to emulate the back of the new model, so I opted to call back to her old model's tattered cloak. This cloak looks to be a cosmetic available for both factions in Dragonflight, but if it never becomes available in-game, the Horde have an identical model in the War-Torn Crimson Cloak and the Alliance can hide their cloak.
