So. Obviously no tridents here. I wanted to challenge myself! (Hunting spears also seemed cool!)

And I am realising I'm pulling ideas from One Piece XD

In the deepest ends of the sea, a member of the Mao clan found this priceless artifact. Once thought to have been lost during a major battle between the marine creatures shortly after growing anthropomorphic features as we had, Hydescovrir was known to strike down anyone underwater. Of course, this spear works best underwater as well. I have attempted to use it on land, however, I found that it didn't work. Instead, it would act more as a lance, which honestly was a bit of a pain. 

Despite this, it has a hidden feature; when someone with emotional fortitude wields it, the nets surrounding the top part will unravel, allowing that person to capture anyone using it. As long as they're wrapped by those nets, they cannot wield a weapon or use magic without being knocked out by the nets. It's pretty annoying when it's used against you, really. I was thankfully saved by a bounty hunter named Tanya Keys, who had been hunting my captors for a while now. You could say that we struck up a friendship, and I decided to give her this spear considering how well she had wielded it. 

One would perhaps call me irresponsible for that, but I believe Tanya Keys will use it wisely. That is why I gave it to her.
