I hopped on league to recieve 3 skins. One was a belated christmas gift from my friend (Firefighter Trist), but the other two were from Riot games (Viking Trynd, and BATTLECAST CHO) Did any one else get lucky? Im so happy!
Basically what happened was your friend gifted you a legendary, and you went on the legendary snowball. you're pretty lucky to have gotten a 3rd skin!
To elaborate on the Legendary Snowball Ona mentioned, it's a special event running that if you get a Legendary+ skin in any way you will get a free Mystery Skin (has a double chance to get a Legendary), and if it's a Legendary it happens again until it's not. Ends Jan. 7th.
