Yet another knife invented by Araska, but easy to replicate. The Relaxer Knife is covered in a poison that, after enough is absorbed into a creature, weakens it's muscles. The reduced tenseness in the creature increases the (raw) damage it takes.
The numbing venom of a Snakebee Larva is potent enough to achieve this effect, rather than paralyzing the creature flat out, so to combine simply combine a Throwing Knife with Snakebee Larvae.
