Thx for checking this problems.
For champions i figured it out and added him to knight`s set already.
Save games i just thought to use old save for your mod (got 1 interesting with 91 int mage

), but it`s not important. There is always new campaign

Voice of dragon fixed, thx for info.
About 0 dmg/kill all stack problem occurred after i kited first 4 islands, and returned to debir and start with it. All enemy were weak/very weak and this happened I didnt edited anything in files. Restart campaign with warrior and all works great, no problems at all. That`s why i ask what could get changed by itself, since i didnt do anything to arena.lua/txt files. Same thing with pet dragon/spell book in new campaign work without problems and i didnt changed anything in mod files

Doesn`t mater, i`ll stick with this new campaign untill figure something out.
One more thing: why make sapphire scales as attack, dragon use it and end his turn. Orc`s commander, orc veteran`s rage potion, paladin`s second wind are all talents that you use and still play with that unit. Why not make azure dragon do the same. Use scales and still attack enemy ?
And you missed azure dragons in sp_lead_dragon (eye of dragon) -10% leadership in special_params.txt
