C13 - C15 (Observation Pool)

Grazuul is a solo threat. My scrag design is merely a re-tooled troll incorporating some close powers stolen from another creature. Take heavy advantage of the water - if things look particularly bad for Grazuul, consider having him leap into the water to spend some time regenerating. He has the advantage over the party in an aquatic environment. I suggest the following encounter for a party of five adventurers:

• Grazuul

Total: 2,500 xp (Level 10 Encounter)

If he does manage to put an enemy to sleep, he is better off not spending a standard action attempting a coup de grace. A sleeping PC (ideally the party's defender) is best left alone so that Grazuul can go after some of the easier targets hanging back.

Treasure parcels 2 and 4 from level 10 can be found in these areas, whether on Grazuul, underwater, or in one of the side rooms.
