Botting/Hacking is risky period. My suggestion to you is hack on a bot account and move items to your main. I've lost several bot accounts, usually they last 2-3 weeks botting 24/7. Others have lasted several months. There is an auto-ban script, although I don't know what flags trigger it. I've been banned overnight during a holiday for example, so I'm assuming no one is actively searching for bots at that time. No one knows how Nexon detects bots, so there is really no point asking. If you're not prepared to lose your account, the simple answer is don't hack.
Hacking can do almost anything you want with some creativity. Break-offs are mundane with infinite sticky bombs and god-mode. Bots finish missions in 1-2mins
