Has anyone tried TAS terraria runs? There are so many places where RNG manipulation would help it would be very interesting. Perhaps bosses could be killed with falling stars or one shot with zapinators.
Cryogen is harder than the mech bosses by a lot for me. Probably harder than plantera, but I haven't tried her quite yet. Edit: Yep beat plantera first try, and failed 3 times against cryo. (I did only have 30 hp when plantera died though)
