[General] How to upgrade items without replacing them?

[stan0033]

I have an item that gives the hero bonus hit points, dodge chance, attack, strength,armor. I need to be able to upgrade this item, but without upgrading it. Because if the upgrade are many I'll find it time consuming to make X items and X abilities for one item-typ. Is there another way?

Maybe I can make with trigger his attribute to increase, and with handicap his health to increase, but what about dodge, attack and armor?

Catch pickup/drop events and add/remove abilities to/from the unit.

Won't the game crash? If I add abilities who are invisible or outside the panel?

Passive item abilities usually do not have icons. Adding them won't crash the game, at least not due to the (missing) command button. Visible passive abilities can be hidden by wrapping them inside a spell book ability, give that spell book to the unit and disable it by Player - Enable/Disable Ability.
