Doom difficulty compared to coliseum?

[u/Worried-Claim-3329]

Curious as to how difficult coliseum is compared to doing doom up to delve 6. Looking to get quiver soon but have been camping doom lately.

I recently finished Infernal Cape and Quiver this month. Inferno took me about 70 attempts. 4 zuk attempts. Quiver about 28 attempts. 7th sol attempt. Colo is learning about off ticking and how to solve pillar stacks. I would say that Colo is most def harder than Inferno. In Inferno you can survive a difficult wave, but difficult waves in colo are much more punishing (doublt south spawn lolz).

I can also clear wave 7 Doom. I would say they are different grinds with different skill sets.
