Spider

"The good thing about this trigger... is that it doesn't use much trion. You can adjust the color of the wire so it'll be harder to spot. You work with the operator with visual support, and make it so only your allies will see the wires clearly."

- Ai Kitora about Spider

Spider (スパイダー) is an Optional Trigger in Border.

Description
Spider comes in the form of a cube and when Trion is inputted, it sends out wires in the direction of hooks that can be pointed wherever the user wishes.

Abilities
The Spider creates wires that can be used to trip opponents or prevent motion. The color of the wire can be adjusted, making it harder for opponents to spot them. With an Operator, it can be set such that only the user's team could see it. It can also be set up with Meteora in a tripwire fashion. Even if it is noticed by the intended target, their distraction by Spider could be diverted to the trap allowing for an effective sneak attack by a skilled fighter.
