Quests:

Introduction:

Skillpoints: 2+1 (the last enemy which exist in the dungeon drops the +1)
Maximum heroes: 1
Maximum completion: 1 (can not repeat)
Unlocks: Tavern (sleep, and recruit heroes), Alchemist (potion shop), Magician (skill-trainer)

NOTE: you can actualy abandone quests. This leaves the dungeon incomplete, but you keep 50% gold, and even more important, any "Blue Potion" aka skillpoint assembled. This creates a very abusable system where you clear the first dungeon over and over, accumlating semi-infinite resources.

NOTE 2: Also did a test-run, andnoticed, that my wounded character started fully healed in the 2nd dungeon WITHOUT visiting the tavern. This is true for any dungeon. Definitely a bug.

NOTE3: if all your heroes die in Hardcore, OR you manage to get defeated during the Introduction, you'll stuck forever in the Village. No Game Over screen, nada. So sad.
