I've not finished Bonfire atm but will tell what I found so far:
Class: Apprentice
- clicking at highscores (fresh installation of KB/Bonfire) -> CRASH
- no crash if any old highscore exists
1st try
Game Type: End game when level 20
- talked to every NPC, collected all chests, got some experience. After winning 1st combat -> Congratulation! You have won the game! End Screen!
- Wow! That was the fastest KB Run I ever had
2st try
Game Type: Endless
Difficulty: Impossible
Companion: Ancient Oak
- Only 1 spell (Lightning Ball). But it works! Lightning Ball together with Ice Wall from rage skills is a good working combo, not overpowered, not too weak, I couldn't believe it. More than this single spell would be too much.
- I overlooked this hint with sawmill and had great problems to get more wood piles. Without sawmill no chance to finish Bonfire.
- The key to play with traps is to build up Trapper award. But the requirements for Trapper are too high, Bonfire has lesser enemies than vanilla.
- We have to live with very low leadership but it's okay. The start is very very hard but this low-leadership-system works!
- The only rage skill in the beginning phase is Ice Wall, it's good enough after learning how to use it well. Later I got Round attack. With having this 2 rage skills the game balance is excellent.
- Main castle must be build up very fast (hint would help) to get sawmill.
- Bonfire is full of kiting situations with well designed room to avoid enemy contact. Very good!
- Companion Ancient Oak is very weak. Only slow spell for close attack. To compensate this he should have more HP.
- Got several crashes only with this try (Lake Fairie, Dryad, Unicorn, Faun). Savegames are here:

- Had to stop this try because i had no sawmill and couldn't get anymore wood piles.
3rd try
Game Type: Endless
Difficulty: Impossible
Companion: Trick Shooter
- extremely hard start

Couldn't find a single doable enemy. There was a big enemy in front of the companion obelisk who could not be enraged to move. So I had to kill this guy with overnumbered units (3 guardsmen) which killed my plan to play all with no loss

After getting Trick Shooter all further gameplay was doable with many very strategic combats.
- not a single crash with this try (Demon, Demoness, Vampire).
- I had 140 leadership and had to play with only 1 Vampire, then I got Knight Boots from shop (+300 leadership!). These random surprises are welcome

- Coffins on battlefield summon too big stack of skeletons (57 skeletons = 2850 leadership when all other units are below 600). 1st one who destroys coffin wins the battle.
- Snow Falcon = overpowered unit #1 with it's skill Cold Stream every 2 Turns. Changing to single use would give better balance. Ini+speed are ok. I tested a Snow Falcon together with undead and demons in my party. Falcon gets -5 morale but still full overpowered.
- Evil Eye = overpowered unit #2 with 3 great skills: Lightning Spell (3 turns), Geysir (4 turns), Summon Spellbooks (2 charges). But that's not all: ranged attack with lightning shock, Vampirism with resurrect. Ini+speed are ok. My advice: kill 2 of it's skills and Evil Eye is strong but balanced.
- Winged Shadow is overpowered too. Very high speed, very high ini. One of them should be reduced to 3-4 and Winged Shadow is strong enough.
- I have the feeling that Demons get too much experience from Summon Spell. They are levelling fast.
- Ruin Castle at Hopland with 200+ rats very easy. Ice Wall in front of Rats and they are simple killed by ranged units. I cannot see any advantage of rats atm.
- u-boat is nice. Thx!
- Skillix doesn't work, you told it.
- Companion Trick Shooter is very powerful at close range, maybe he must be reduced.
Conclusion
At least in my 3rd try I got no crashes. No problems with quests, no problems with NPCs. But I focused on gameplay/balance/units. And this was great, I learned new tactics and had a lot of fun when testing. Bonfire was hard but I could go to lvl8, discovered 7 of 9 isles. Except 1st combat with overnumbered trick all was impossible/no loss/no skills (except concentration 1). But I used a Snow Falcon and an Evil Eye. In Bonfire combats are much more strategic and flexible than in vanilla game. Random is exciting. Each new game results in new strategies. The replayability is very high!
Thx to Bonfire Duo for a really great job!
