1) you can learn any skill deep in the skill tree and then with the brown books remove the previous skills you have learnt in order to learn the last one and save skill points
2) the armor durability has some changes, dont know if its on purpose:
the armor durability goes down only when you die. in the original game the durability went down just by reciving damage. Example: after clearing 50 floors of cc dungeon almost the full party had the armor durability under 50%, thats why de bonus floors exist (to repare your armor)
the armor durability goes down in the pvp areas and duels, at least in the tw server the durability did not go down in the pvp zone/duels/rank battle
3) wonder buff play dead does not dissapear once the player gets up, you can kill any mob while the buff is active and he is not going to fight back
4) the dragon class have a reflect buff bugged. if you spam the buff it get stacked, once you stack it four/five times the energy mobs dies instantly when they attack you
