THE TRENT WAR --- a new campaign!

[Ghoul King]

I've not found a larger pattern to the crash. In the case of the Dress, for example, it's a Swordsman that crashes the game, but there's other Swordsmen in the group that don't crash the game. And the unicorn Hero didn't have Swordsmen at all. The only consistent pattern I've noticed thus far is the part where if a given battlegroup causes a crash once, it will always cause a crash and always with the same stack.

I've actually not had any other form of crash, which is a bit surprising. Red Sands has more random crashes, or for that matter Warriors of the North. I went in expecting random crashes, and haven't had them.

As far as the Dragon Toy goes, maybe the problem is that you copied the Item code at all? I've not messed around with King's Bounty modding, but my understanding is that stuff that's already in the base game generally doesn't require a mod re-specify its existence. Maybe what you're doing is, as far as the game is concerned, making a new set of Items, rather than importing the regular set, and then the combo Item code gets confused by this?

Though tbh I actually prefer the idea of the combined Item just being a separate Item. In the base game, the combined Item is generally difficult to justify denying yourself access to the Shovel and the Boots; like yeah sure Lava Call, Fiery Phantoms, and Dragon Dive all get to do more damage, but not THAT much more, and missing out on extra chests and the utility of bonus pushing is painful.

Regarding Diplomacy; +10 Defense might be a bit much, given it's applying to Levels 1-3. If it only applied to Levels 1-2 I'd be more inclined to think it cool but not necessarily amazing, but a lot of very solid army formations end up being made entirely of Level 2-3 units anyway, so at that point it's bordering into being ridiculously better than Resistance -while still allowing you to potentially steal enemy units!
