The dungeon is enormous, and you're given 4 firewood.

You are looking for a specific room and up against really annoying enemies that can teleport you to random parts of the map. Mission 3 is either really hard or really easy. Bring your A game here because you'll be up against multiple enemies at a time that can each take two actions (like bosses). Several boss fights, and you have to really decide when you want to camp because in my opinion it can make or break the mission. New enemies, but many abilities similar to ones you've already seen. Mission 1 is straightforward, progress through and fight a boss. Ancestor's portrait also accelerates this, particularly if there is a certain hero you want to use and are trying to level him up ASAP. So if your hamlet is established to the point where the only thing lacking is level 6 heroes (but you have the money to train/equip them) it has gotten a lot faster to do so.

To your relief, they've made it much easier to level up. That means tha i'm pretty much condemned to grind again in order to finish the last portion of the game.
