Here's something stupid simple, at least probably stupid simple for you.

I'd like to build a quest where certain doors will become opened when you possess a certain number of a particular item. Basically like the system Final Fantasy Legend 2 uses to determine if you could move forward in the quest by the number of Magi you possess. One method I thought of would be to use an item that is tracked. Then when that item gets to a specific threshold, the script would add a "key item" invisibly into your inventory which would then be used with the "Authentic Dungeon Doors" Script on PureZC.

It would be preferable if I could somehow do the same thing without using item slots though....
