jsut as a reminder once you mq your will be rerolled back to lvl 1. at wich time you wont beable to equip your high lvl gear.
meaning in able for you to lvl again and go back up the ladder you need to hold on to low lvl weapons and armor and chamrs.
please check out my charter NightIvIare hes a bit different then yours but the idea of holding all your geat is apperent. found here
http://forums.d2jsp.org/user.php?c=3&i=273086&p=68757cause you ahve sold off your gear all is no lost. you can keep lvling as you are now. and whn oyu get up there buy cheap Extra items slot gear. equip it and but weapons, armor, and charm this will give you extra room
tehn buy lvl 0, 5, 15, 25, 35, .... and so on weapons.
as for armor and charms you can get by with less intervals.
unless you going up only once or muling on other charters tehn nvm mind this post.

hello an welcome to the slashing comunity. wish the whole Anima Templi guild luck
