We've datamined some fun cosmetics on the 10.2.5 PTR with a vibrant enchanting nature theme — Monarch Wing back pieces and Eternal Roses as a helm!
The Monarch Wings cosmetic back transmog is available in four colors: Wings of the Emerald Monarch, Wings of the Tourmaline Monarch, Wings of the Amethyst Monarch, Wings of the Amber Monarch.
The Eternal Rose cosmetic helm transmog is available in six colors, all with interesting flavor text.
If we look closer at spells that share these new rose icons, we can see that they'll offer an outdoor buff. All the buffs increase stats by 10% outdoors, but they have different names reflecting the color and mood of each flower.
