Those are permanent items. Look in the object editor under items and permanet. Then copy one of those, change name and icon to your choice, and set the attack or defense value to what you want.
Like claws of attack, after you copy it you can set the new attack value to +1000 if you like or what ever.
i think your talking about the inventory. you can make a copy of the inventory ability(in the object editor under abilitys) then change the number of inventory slots to 2. then give this ability new to the unit you want.
Guys just a heads up I am going to be shutting the site down soon. I am just waiting on the NUON people to decide whether they want to transfer forum data and keep the discord. My email is [email protected] for anyone that wants to keep in touch and I have a facebook too. I will make an official post later. Love you guys and will miss everyone!
I'd rather personally just own a backup of the Nuon data than see it go to AtariAge honestly. If it gets enshittified as per usual, or if some of the "regular" Jaguar folks get there, it's not gonna be fun
