Same luck here...
Wasted all my saved up ironite on 10 Souls...red eyes...blue Valk(dupe ofc.)
Plus i started to rush LoL (auto battle tempts you to do that after the troopers are done), but after about 3 SoT refills i did some thinking: To win 100 LoL3s for 6 SoT you need 210 ironite and to win 50 BNWs for 8 ironite you need 150 ironite. finishing those for 360 ironite will award you with 500 fragments=2,5 souls...
So at the end of the day you are better off just buying 3 Souls for 300 ironite, get stabbed in the eye by the blue eyes and save your phones battery....where is the logic in that?!
