I stole Frostallion's Double Blizzard Spike and put it on my Icelyn
There is no fruit for it in the game, so I got it on her by breeding. Starting from Frostallion, it took about 1000 eggs to get the right combination of passives, potential and the double blizzard spike skill but I finally got it. In the end I still had to use 3 life fruits to get her HP potential to 100.
