As pointed out before... people only look at the "Magic Stats" placed on the item, not the end damage / defense that it will show.
If you want to do the work and figure it out exactly, then you will have to use the Ladder Slasher portal and click either:
Weapon
Armor
Charms
Find their tier level, find corresponding numbers you want... IF... the item has X% enhanced effect, then calculate them with the
corresponding numbers [remember to round down] to give you an exact number. Note: as for Dex/str items, I am unsure if they
will automatically change the value of the item worn or in inventory.
If you are talking about the price of an item when you bought it, then you have to go to your character screen [on jsp], right click
and select View Source... you will have to find that item and the ID code number [it will be in a string of words linked to that specific item],
Copy this number... go to your Forum Gold and use the "Find" function [think it is CTRL+F] and paste that ID number... then press enter.
If it does not show up, go to a previous month and do it again, and repeat until you find it.
Or you can find the ID code number, go to your Forum Gold, click on one of the links [sold items] and with the new page open, just paste
the ID code number where the other number is, this should give you direct access to it.
Hope this all helped... sorry for long winded post.
