The first one is one that was just recently announced: Headhunter Master Yi.
It's a fairly neat looking skin, and will apparently have new spell effects on two of his moves. Is this his legacy skin? No. Is it worth buying? Maybe, especially if you're a Master Yi that likes to jungle. When is it coming out? My guess is this upcoming Tuesday.
Up next are three skins that are currently on sale.
Cryocore Brand (regularly 975 RP) is only 487 RP!
Golden Alistar (regularly 390 RP) is only 195 RP!
Perseus Pantheon (regularly 975 RP) is only 487 RP!
Those three skins will remain on sale until Feb. 10th, so if you're interested in those champions, my suggestion is you act quickly.
That's it for Skins of Interest. Soon I'll analyze the free champion rotation for next week.
