Dunno about "already". Its taken us years to get to this point!

I loved the end of adventure 9, although the PCs got lucky with a prismatic spray (getting the fire result, and then finding that fire magic does funny things against it)

Adventure 10 was a bit of a struggle. Lots of trillith with arbitrary powers. My players hated knowing nothing about the enemies in each fight.

I gave Freedom SR 26 and reversed the natural armour and deflection bonuses. The fight that lasted 3 weeks. Serves me right for modifying a CR 20 creature on the fly.

I was tempted to let them fight Annihilation but even for my optimised party it would have been a massacre. Unfortunately the non-fight version was a bit vague in the adventure, and (maybe I missed it) forgot that any party will be able to teleport.

In 11 they are enjoying squelching their way through the innards of the Tempest.

Might do a review of the entire campaign when my delux hardback turns up.

Holy crow man! I hear you're already in the Tempest! DETAILS!

After a long break, my group has finally completed adventure 9. We're doing a 'mega session' next weekend to start the Catchup process.
