Teras Kasi Archive

I have unarmed 3 done and working on 4. I just wanted to know if i can use any kind of weapons with unarmed. Or do u only start to use weapons if your Teras Kasi?

You can use VibroKnucklers right now if you would like.The damage decrease for not having the certification is not bad at all, and if you equip them you also attack faster.
