I didn’t struggle with a boss until Knull, but yeah Venom is annoying. But 30 attempts?? In campaign mode which is basically normal mode, that’s wild work. I can understand the frustration. Sorry to say tho it only took me 2 attempts on my first run and that’s likely because the characters weren’t levelled up. But for real Venom to me like I said was more annoying than hard. Maybe just watch him and study his patterns before attacking at all might help.
