Harpoon Guns

I think the Harpoon Gun should either get a BIG buff or another Variant using some resource you can get in the Abyss. Im tired of trying to get the Ancient Pond Swarm Guys, to get the Gold Card same with any other Creatures in the water. Takes like 20 Bolts and at that the Resources to make the Ammo is expensive.

Please let me know if im just dumb or others feel the same.
