It costs 61k gold to buy the Ghost tower and all 12 Ghost skins, cuz I had 60k gold and had enough to buy the tower and 11 of the 12 crates and I was 1k short so I did a normal TB match to get the last 1k I needed
Believe me when i say: Cryo ranger is good. I was just able to beat intermediate with it while normal i would die fast using it. It when from having trouble freezing Boss1 to freezing Monsters with Eaze (with like 4 top max and 2 top max). I do suggest not using it at all on bosses. I was nit even able to slow predator down.
Imma be honest about stealth reveal in current state. I don't find value in stealth reveal anymore, since all towers we use in current meta have thier own stealth detection anyway.
