First things first, there will be no items with pluses on them. EVER.
Now that's out of the way.
In your Profile template, you should see two bars for items, the "Special Items" and "Equipments".
Quickly put [Special Items] are items which are special to your character. This may include but is not limited to lockets, bracelets, some weapons, a pendant and the like.
[Equipment] is much more simple, as you may very well have already figured out, these are your weapons, gear and stuff. Don't forget to add the items (amount of potions, etc) here.
Now on to the questions of weapons with stat bonuses and cash items. YES we do allow you to have them provided you explain WHY you have them or go through necessary quests to get them.
These items will not have any bonuses whatsoever. That means having a [Death Guidance] won't give you a glowing, imba sword which will magically increase your strength and speed. It'll just be a beautifully crafted sword with a fancy name.
Unless your weapon is of course related to your skill (like the Sealmaster's Flagwand).
Some weapons can be heavily customized but requires an RP with a Smith class to create it first.
As for the God equipments, leave them to the Gods.
