Bandit is a great character for deep runs in Megabonk thanks to his starter weapon, the Dexecutioner. Making a good build for the Bandit is about leveraging Size, Projectile Count, and Crit Chance, which are the three stats that affect the Dexecutioner.
Here's the best Bandit build you can use in Megabonk, along with some alternative Weapons and Tomes picks if you can't find it all in a single run.
