The Arcane Archer Mortal Online 2 build uses both mounted archery and mounted magery. You will use this to take down horses with mounted archery, and then can choose either magic or archery when the player is on the ground depending on the situation. With full mounted magery you will also be able to fully heal your horse, letting you back off and reset the fights whenever you choose, making you a nightmare for any other mounted build.
This build also is a full necromancer/ritualist, so you will be able to summon walkers and have a risen undead horse and undead pet. This is easily the strongest solo PvP build, and can easily take on multiple players at once. It is also very powerful in PvE, for taking down animals, monsters and bandit camps.
The one limit to this build, it fully mounted, is great for solo/small content, but falls off in big groups, as it can’t be used in dungeons or sieges, however it excels in any mounted combat situation.
