I am a newish GM. Me and my party had about 5 sessions and I think it is the time to give them better weapons, but I could no find any tables for lvl 4 characters or anything similar. Is there a need to upgrade them, like giving extra damage or change the die from 1d10 to 1d12 or will it be balanced by their abilities? I know, that +1 weapons exist, but they look pretty weak and how does one make it +1 anyways? Any tips? (similar struggle with armor)
