The topic pretty much sums up my question. I have not yet figured out how the gun operates aside from the fact that it creates Portal portals. The weapon description indicates that it deals 250+ base damage, but how is that damage applied to the monsters?

The gun itself is actually not able to shoot, unless you use the skill "Piercing Shot". This is where the damage modifier comes in to play, as it increases the damage done by the "Piercing Shot" skill. As far as I know, that is the only usage of the damage modifier displayed, when using the Portal Gun.

  • yes, piercing shot + portal gun is an awesome combination. If you upgrade it a few times, you can easily hit 10k damage with your piercing shot.

  • Well that certainly is disappointing news. Not exactly all too useful for a huntress for soloing.

  • @Sorean That is right, but the portal gun is extremely effective in multiplayer. Sending enemies walking back and forth in front of a wizard's towers, for instance, or unleashing piercing shot in tight spots can make the difference between winning and losing. Also, as a last resort, you can dump a whole lot of enemies straight into the abyss/lava but you do lose the mana/items they drop.

  • I never thought about dropping them into lava/abyss. Thanks for the tip, it would make some of insane soloing easier.
