So Petrify wont work since all mobs are same level as I am. But you're right I still can get up to 10 Enfeeblement:
1) Slow (ice spike)
2) Deep Freeze (Ram's Voice)
3) Paralyze (Mind Blast or Dragon's Voice)
4) Stun (Bomb Toss)
5) Silence (Flying Sardine)
6) Peculiar Light
7) Addle
8) Break (Heavy)
9) Offguard
10) Song of Torment

Now the problem is actually winning without any heals... I was able to complete Act 1, but I keep getting defeated by the add's poison in Act 2. Dodging the line AoE is already a pain. The adds just make it ultra difficult. When the adds appear, I silenced the Golem big spell. Then I tried to freeze the adds with Ram's Voice, and then Peculiar Light, and spam Plaincracker since they're weak with earth. But it didn't take them long to release themselves, and use like 5 poisons on me. Without my heals (3 star), I died almost instantly. Any tips?
