Perimeter Tripcaster Perks¶

How to Use the Perimeter Tripcaster¶

The Perimeter Tripcaster has a lot of utility to it, since it has both Shock and Fire Tripwires, meaning you can use those on any machines that are weak to those elements. They’re not the best, since Tripcasters are more for setting up ambushes than anything else, as they might be a bit slow to use during normal combat. The third ammo type here, the Shieldwires, does have a bit more practical use. It protects you from projectile attacks, but if it takes too much damage over time, then it will explode and deal explosive damage. Note that you can also trigger it with your own attacks, so it can also be used as a trap.
