Einherjar has real custom classes with real custom skills that feel unique and are fun to use. It doubles the amount of classes available, bringing a whole new layer to PvE and PvP, making even things you've done playing RO several times feel fresh and exciting. There are other custom features such as Enchanted ornaments, Custom maps, tweaks to vanilla features, etc. The server is being worked on mostly by one person and the work is massive, so don't expect things to be perfect or full of people

OriginsRO has a few things that set it apart from other servers. It's been up and running for over 5 years with no wipes, it has a good economy where your zeny is actually worth something, there are improvements to encourage party play with other players and not just use 10 alts, but most importantly, they take no donations. No cash shop of any sort, no VIP system, no p2w, no bullsh*t. Come join for a hardcore classic experience, or just a casual social game.
