I'll be moving your post it's in aion not iris. but first things first WELCOME!.
Level change quest is at lvl 30 you kill 3 elite monsters to change level. Gladiator and Beserker are really good melee dps classes. Big bursts of damage. ;-) Well you can get good weapons from dungeons, raid bosses, and from mobs with low chance.
Max level is currently lvl 75 for us. Sedy our admin has made custom stat gear and has a custom dungeon for you for custom accessories.
Here it's best to run quest the rates for the quest are good. There are vendors in front of the fountain you can buy weapons and armor from for Mighty Trophies. You can't break your weapon nor your armor when enchanting it.
We have a cash shop vendor that is the basic cash shop items from retail. You buy those with Tears. The same tears from the tears of arcana event from retail iris. That NPC is called May. You can accumulate those by being online for every hour you get 2 tears and you also can vote which there are a lot of voting to get tears. You can also get more boosted costumes and items and mounts from NPC Lord Sedy with donation currency which don't worry you don't have to donate you can buy with tears or gold from people.
Best thing to do is find yourself a guild also. This game is a lot more fun with guild mates. XD
