This thread is making me want to level my 4th warlock.
This, NCT all the way.
If you want to test the damage you would do on Big Bells, you can just go hit regular Alarms to test your gear setup.
They take exactely the same damage, they just have way lower HP and are less dangerous in general.
^This. If you can't handle Big Bells with your gears, start at second level, killing Big Bells and Neo Punks. The EXP is worse, but it's WAY easier to level. Also, you can stay at scarabas until more than 150. Spotlighted scarabas keep giving a decent exp even after that, and will be easier to kill/not die.
