Order Details

:  Well, uh.. it's a little outdated. You stick explosives down the end, then you fire the explosive. With more explosives. If you're trying to reduce your injury rate, don't use these.

Other than its archaic design, the mortar tube is actually pretty decent if you can get a lot of them in a battery. Can blanket a big area, like [REDACTED]. I suppose you can beat them with the tube afterwards.

Character SynergiesEdit

  • Since this item uses its damage output based on the damage done on an enemy when it procs (not the base damage of the character), then stacking this item is extremely powerful together with characters that deal a huge amount of damage on an attack. It's hard to pull off because mortar's chance to proc is linear.
