Betting im the first on this.. It's incredibly hard, and annoying as some of the challenges are just plain frusterating to attempt to 5star.. Im confident a few are actually 100% straight impossible. It's pretty clear they didnt test some of the variations to be actually doable. Disruptor, Shortcuts and Collosal crystals in particular, Short cuts im quite sure is straight impossible to 5 star even on the lowes setting, even with godmode characters.. Other 2 would be insanely hard but potentially, with a lot of luck.
I mean all the base one seems quite balanced and beatable with 5star, usually even at max cr.. But the variations like drop the time limits by a ton, then add mobs with 200,000hp and crazy rules that are impossible heh.
Anyways heres my scores - try to beat em =)
PS: Gold star = all 5 stars and ran it on maximum possible CR.. AKA: Crushed.
Favors - my older non tr actaully has more, but ran my stronger tr bbn on these.. Actauly woulda been a ton easier on caster, but eh bbns are great at rushmoor, not so great at the other 3.:
Oh yea and after all of this work.. I still dont have enough ingrds for a single epic item.. They went hardcore on nerfing the reward rates since i ran this on lam.
EG:
Lammania disruptor, very good run: 4000 necrotic charms.. (cost for wep is 600)
Live.. same score: 40 necrotic charms.. nerf'd by 99% lol.
Most others are nerfed by 75%-90%.. They really dont get the idea of baby steps or moderation.. I mean a cpl on lam were too high and coulda used a -25% drop, but most were actaully fine.. Go big or go home! hah.
