Alright so let's get caught up with all the new shit for any newer folk/potential interested people.
Notable stuff mostly, demonic weapons. We'd need a max talent blacksmith to make these things, and you need a max relevant talent to be able to wield them (Two handed swords need max close combat, Cylinders need max battle alchemy etc). They also need people capable of running lord missions, the highest difficulty past elite, and probably something that makes peaca wither up and die, as monsters apparently have upwards of 60-70 prot in them. Big deal. You also need about a hojillion materials from those missions per weapon soooo yes. End game content woooaoaooaoaoaoaoaaoaoaoaoao
Daily AP missions! Basically do both the daily shadow missions and you get 3 AP a day. Do one and you get 1.5 AP a day. Note you keep the .5 in your inventory as 5 "mini 1 AP potions" in a sense. This is a huge deal. Daily AP really speeds up skill progression and they're usually not terrible to do to boot.
Lower exp amounts for levels! You can now get up to 30 and maybe even 40 in a day no sweat. Another instance of speeding up skill progression, this is great as some of the new lord missions are absolutely rediculous and not having to grind for fifteen years to stand a chance does a lot to make them more viable.
Future content? New questline involving iria, called "nightmare". It would appear shit is going down. That's about all I know. Also hybrid talent skills! You can only get them if you're up to an apprentice in a hybrid talent, like, for instance slayer. New skill and it raises both of the talents that are involved in that hybrid talent.
Here is all of them. Also one here. Presumably more hybrid talent skills will follow with time.
The patch after that adds a few new life skills that are all in korean so I know nothing about them. If anyone would like to take a shot at translating them, the links to the skills are
here. Adds some new stuff to iria which is much appreciated.
The patches after that, while listed, are shrouded in the mists of mystery and dreams.
