Scripts

apparently, the game doesn't care about the coefficient...

I have these questions: how do I reserve a scripted hero? And how do I specify a particular arena in StartCombat? I tried writing a path like "/Arenas/CombatArena/FinalCombat/FinalCombat.(AdvMapTownCombat).xdb#xpointer(/Arena)", but that's obviously not it. I need an arena with an Inferno castle, and ideally, an arena from the last mission in the original campaign.

Thank you. No matter how many times I check, the bug doesn't manifest itself; only players in the forum wrote about it, so I can't check it myself.

You can reserve a scripted hero by temporarily placing a mod that unlocks these heroes in the data folder. There is also another option: create a non-scripted hero, in players>player_number>ReservedHeroes (property tree), click "..." on the desired hero, and select Shared with the scripted hero.
Combat arenas are objects of type AdventureFlybyScene.
