Snare Grenade

A type of arcane grenade often used by shock troops and anti-personnel operations.
When thrown and landing on the ground, the grenade releases a web of ephemeral strands in a radius around it. Usually about 5-8 meters.
Should any person or thing touch one of the strands, they will immediately latch on and tighten, pulling the grenade directly against the target's surface. Moments later, the grenade will detonate, more than likely killing the target, but always leaving them combat ineffective.
