How to Use the Perimeter Tripcaster:

This tripcaster is all about setting up ambushes. The Shock and Fire tripwires are great for exploiting enemy weaknesses to those elements. While they might feel a bit slow for direct combat, they shine when you're anticipating an enemy's path. The Shieldwires are surprisingly versatile; they can block incoming projectiles, and if they take enough damage, they'll explode, dealing damage to anything nearby. Pro tip: you can also trigger the Shieldwires yourself with your own attacks, turning them into a neat little trap!
