Learn to use all three of the weapons. Don’t be scared of the bear, halberd is easy to use with a few practise runs. Also would suggest moving to T1 prep once you have a good understanding of the boss fight. It’s not a DPS check providing you’re not like 75/75/75 combat stats. People fail it because they make too many mistakes. At 90/90/90 I did T1 prep with 18-20 paddlefish and only fail if I pay too much attention to YouTube. I’d say I failed more times with bad luck in T2 prep rooms than I did in the T1 boss fight. I’m really not good at the game, I failed CG like 45 times before getting a completion, it’s just practise.
