Just to confirm, are these species-specific weapons? For example, the Endeavor Helmet or the Kora Sword. It's likely they are, but given that it doesn't appear to say anywhere that I can find, I thought I had better ask just in case.

No, I don't believe any weapons on the site are species specific. There is a kora weapon thay is slightly stronger if a kora is using it, but the weapon really isn't worth mentioning

Alright, that's good to know. Thanks a lot!

No problem :) good luck!
