I know it's almost impossible to sell leech at RoR4 but is the EXP difference there compared to Ulu2 worth leveling up my HS mule to Bishop? I'm about 80 TMA away from 1 Hitting Petris so I just want to grind out those few levels as quickly as possible!
Ulu 2 wouldn't get you to one-shotting petris as fast, but the money gained there (in the form of Perfect Red Cravens, thief tops/bottoms, selling leech) wins compared to RoR4. In terms of EXP, Road of Regrets would win and is in my opinion a far more enjoyable grinding experience because of the map layout and OST . If you're more worried about leveling faster rather than gear improvements and don't mind overleveling your HS mule, I would seriously consider staying here. Keep in mind there's always the option of looking for a bishop grinding partner instead of using your mule!
i believe that if you're not selling leech, ror4 is more mesos than ulu2. ror4 has red cravens, female warrior bottoms, and int scrolls.
The chances of finding a consistent bishop that has completed that much of the ToT questline is rare these days. I'm going to consider leveling my mule because of my upcoming Hero and its crucial need of hs for end-game grinding at Oblivion 2-4. Also, I applied for your guild please check it out
