I'm currently trying the scenario that was included with FRUA: The Heir's to Skull Crag. It's harder than I thought it would be. Being ambushed by a large number of Ogres, among them several Shamans that cast Hold Person is no fun when most of your characters are held before you have a chance to act.
heh you know, I have NEVER played that mod.
You haven't missed much.
The module is obviously designed for players with maxed out characters who rest after each battle, since the party is constantly being surprised by traps and ambushes (Ogre Shamans that immobilize most of the party or Rakshasa that kill most of the party with fireballs and are almost impossible to hit with lvl 6 characters) , which can only be survived by metagaming or luck.
If it wasn't for the fucking ambushes it may have been worth finishing.
