Dear fellow players,
We have stumbled on a rotten egg here.
Bought the game and me and my girlfriend are lovin' it!
But here comes the tricky part.
We currently have only the CORE game.No expansions.
We want to do a Campaign here.
We started off with First blood->Fat goblin part 1 ->Fat Goblin part 2 (heroes which is me lost) .
Now should we play Frozen Spire ?
I also want to know did we do the right thing,since in the second act of Fat Goblin I lost pretty much on the 3rd round.
Thank you.

Here is how this is supposed to work:

Progression in The Shadow Rune

• Players start with the introduction quest "First Blood".
• After completing the introduction, all Act I quests become available. The winner of a quest (heroes or overlord) may choose one available quest to play next.
• After introduction and 3 Act I quests have been completed and the heroes won at least 2 Act I quests "The Shadow Vault" is played as the Interlude quest. Otherwise, "The Overlord Revealed" is played as the Interlude.
• The outcome of the Act I quests determine which quests are available in Act II: The Act II quests listed on the left side of the Quest Log are quests available if the heroes won the corresponding quest in Act I. The Act II quests listed on the right side are available if the overlord won the Act I quest. All Act I quests not played during the campaign are considered to be won by the overlord for purposes of choosing the corresponding Act II quest.
• After 3 Act II quests have been completed and the heroes won 2 or more of those "Gryvorn Unleashed" is played as the Finale quest. Otherwise, "The Man Who Would be King” is played as the Finale quest.

The Fat Goblin

Losing encounter 2 as heroes in round 3 is possible but very unlikely:

Splig can only interrogate 1 prisoner per turn, he needs to pass a strength check (which is not very unlikely, 72%) to do so. After that he needs to move a minimum of 18 spaces to leave the map through the entrance. Within 5 move actions (= end of round 3) he gets 15 movement points. Thus, finding Frederic in the first try, no heroes blocking the way and at least 1 Dash is needed to successfully win in round 3 as OL.

EDIT: Corrected my post thanks to Atom4geVampire.

"After introduction and 3 Act I quests have been completed, an Interlude quest is chosen by the heroes if they won 2 or more Act I quests or the overlord if he won 2 or more Act I quests."

If I'm not mistaken I don't think there is a choice here. It's option A if the heroes won 2 quests, option B if the OL won 2 quests. Neither of them gets to choose which quest (even if they won 2)

Atom is right. I messed that up. Will edit my post. You really should continue that proofreading of the CRRG, Atom

That's correct. In Shadow Rune there is no choice. The Interlude is fixed based on which side had won the most Act 1 quests prior.
