Need help with my BBEG fight

[Odysseus]

From the WOTC site there's this map

Or there's this one

Don't forget multiple ways into the cavern at multiple elevations, passages running from each entrance to each other "behind the scene" and mooks to shoot from them (wizards?).

As far as having the set move, why not make the whole cavern part of the "lock" so the process is started as the PC's are in the room, and the BBEG can laugh maniacally as PC's need to make Reflex and Balance rolls to avoid swinging chains and whatever hangs from them.

I like the Dragon's Grave map, maybe with an entry similar to that column chamber in the Flooded Sanctum map.

To make this interesting, you probably want a very large chamber with randomly placed columns, blocking motion. Make for wide-open areas (better for Huge creatures to move and attack) and tighter areas (better for Medium creatures to snipe and hide). It helps if bad guys can keep the tighter area blanketed with area spells like fireball, giving the party options like:
1) take out enemy spellcasters to make the tighter area more livable to non-rogues, or
2) fight out in the open for all-out melee goodness

Helpful if a high ledge or three across the open area for bad guys to use. Note: must provide illumination for ranged attackers and spellcasters, perhaps keeping *only* the tighter area illuminated, dunno

anyway, sounds like fun, good luck

Well since it all hinges on the stars being in alignment, why not have the whole cave be one giant astrolab/clock (visualize that thing from Augra's cave in The Dark Crystal).

Then there could be spinning gears, weighted chains dangling here and there, giant planets rotating around room, etc. And the whole time the PCs can see the planets and stars wheeling closer and closer to the necessary alignment that releases the god. Insert some constructs as part of the mechanism.

The challenge would be helping the players visualize such a complex setting.

"Running" with the stepping stone idea, you could have each stone marked with some sigil. If the PCs can figure out the pattern, they'll know which stones are safe; the other stones of course would collapse under foot, spilling the character who stepped upon it into the icy water (and ravenous jaws) below.
