I appreciate your time for the reply. I just want to make it clear. The map has an item Scroll of town portal which the AI bot must buy from the store and the item is just hidden somehow it wont be shown in their inventory.
you could think about using a tome(like tome of str+1 but change it so it doesn't add str), changing the art and tooltip and stuff... then implement purplepoot's idea
instead of using a bool.. if you want to be able to hold multiple tomes, make it an integer & every time you buy one it adds one to that integer... then every time you use the skill it subtracts one, with the condidition that the integer must be atleast one.
*note* this is COMPLETELY do-able in GUI because i have used this before
I'm still having a hard time to implement this. What I mean with hidden slot is that to go over 6 item slots. There are only 6 item slots in warcraft III, I heard you can go more than 6 item slots, but i just need only 7 where the seventh is hidden.
