Upgrading Hero to a better Hero (Rarity)

[HellfireJin]

Hello, my question may be a bit complicated. I am creating a RTS map. the Heroes in this custom RTS will have different grades of rarity (Common, Uncommon, Rare, Epic, Legendary, and Mythic). Each Hero will start out as Common. after gathering enough resources you will be able to "upgrade" the Hero to the next rarity, giving better base stats, access to more powerful abilities, etc. My question is: how do I accomplish something like this? As a Hero there is no "Upgrades into" under the list of options in the Object Editor portion. It's there for buildings, but not for heroes. would I use something like the Berserker Upgrade and change it to the selected hero? I also want the Hero to have said option available on the hero and not through a building (like the barracks would have upgrades for units). any help or pointing in the right direction would be extremely helpful, and I thank you!

You can use Chaos or just do it the way we used to - with a trigger.

Create a new hero, adjust the xp, give him the items, remove the old hero.

You can make your hero sell a unit that serves as the button for upgrading.

Just keep in mind that there aren't a lot of slots for buttons on the hero.
