Re: Argon Crystal

Hello, I need your sugggestion on efficient use of resources, particularly the Argon Crystals. I have learned recently that it decays, and realized that it would be a waste to not use it given its rarity. I've been looking for weapons on the wiki that need Argon Crystals, but I could not decide which one to build. Should I go for the Tonkor, or something else (I have 3 in my inventory at the moment)? Thanks
