Fellow GMs! Looking for advice/inspiration on designing encounters for an underground dungeon crawl that takes place in a forge under a mountain. I have the general story beats mapped out, but I am having trouble coming up with encounters, puzzles, or mini-fights that fit the theme (crossposting to daggerheart sub to get actual feedback haha)
For context, the party has been transported to a forge deep within a mystical mountain, and to escape, they must ascend a long, winding path to the summit. They will be transporting a magical flame that they must keep alive throughout the ascent (this is based heavily on the quest Zuko and Aang undergo in ATLA S3E13: The Firebending Masters). Their exit will (appear to) be two giant bronze doors that they must place the fire within in order to unlock. This will lead to the big battle encounter in the session, where they will essentially be fighting a warforged titan that becomes animated by the “flame of life” the players have been transporting.
Really just looking for fun, thematically consistent puzzles or flavor that seems appropriate to fill out my 5-room dungeon lol. Also, apologies if this is rambling and incoherent, still getting the hang of both GMing and Reddit, haha. Appreciate any advice!
