The Chosen Ones

So I just downloaded TCO, and after going through the introduction and starting chapter 1, I see the combat kings in my inventory. They have a cost of 250 mana for some reason, so I level up until I have enough to use them, and when I click on the combat king in my inventory, my armor becomes invulnerable, and I start exploding, taking damage, and then i die. Anybody have any ideas on how to fix this or what might be going on? This might not even be a bug and I'm just screwing something up.

Also, I am able to use them when they are in the boxes, but then the combat kings dont appear in my combat kings tab.

I am using the one from The Hive, https://www.hiveworkshop.com/threads/the-chosen-ones-1-0.83535/ The Chosen Ones 1.0.

I think I got it to work? I put the combat kings into the storage boxes, and then just continued the campaign for a bit. After a couple cutscenes, the mana cost disappeared from the combat kings and using them works. I have no idea what went wrong since if I start a new game, it still kills me.

I was refering to the warcraft 3 version, i think this bug has to do with you using 1.3.0 or similar. In general I suggest using versions 1.25 or 1.26 which are the most stable in my opinion
