1st: Free NT was temporarily closed since the test period ended. It's currently being discussed at Staff section if it was a good thing or not, and you can leave your thoughts about it aswell here:
http://www.maxko-forum.info/viewtopic.php?f=117&t=340592nd: In order to help the newcomers abit, we added 2x Talos into each boss land (1x near kabald - patka /// 1x near alino) that drops +3 Iron Belts.
3rd.: For the same reason (to help newbies) every +3 unique can be upgraded from now on to +5 (we are skipping the +4 stage).
All you need is 3x from the same +3 accessories, an "Accessory Compound Scroll" (can be bought near anvil at [Scrolls] Charon) go to Anvil, select "Compound Accessory" option, put the four items there and you will get a +5 accessory.
