And at level 112 lot players do not leave serpentines cave, because they have full teams there and do not want to leave. That is not a good idea. You really should go grind to river map with team or not. Serpentines give like 0.001 per kill, muckers in river give 0.005 per kill and those other aggro mobs give 0.006 per kill. Yes they are harder to kill in Twelvesky2, but even with more time to kill you get at least 2x-3x faster leveling and team in serpentines cave is not faster, unless you just stand there and chat XD.

105 rares are nice, but once you hit level(12sky2 Gold) 112 better sell them and use 112 uniques, upgrade them ofcourse if have money and mats you even can try going way past 60%, because they are a lot easier to get than rares. 105 rare attack weapon (perfect) has 777 dmg and 96 attributes dmg - 112 perfect unique has 844 dmg and 113 atributes dmg. We even calculated that 105 60% +4 aoe weapon does less dmg than 112 unique 60% +1 aoe.
