legit can't get over how bad Ultimatum is in POE2, not only do you have to do the last version 4 times, once to get each fragment to access the boss, then again with the fragments, there's basically no way to get an edge at all when doing it. Even Lab in POE1 had a way to get an edge with Dark Shrines on every run. Sugmas trial is somewhat cheeseable with the merchant being a fairly consistent way to get power, though it's still trash as a full melee build if you don't have one shot power levels.
