hello everybody! My party is in the Fane, they will soon meet Azarr Kal. Any suggestion to how to make the five dragon heads of the room effective and useful? The handbook suggests to give, i.e., fire immunity... but any more specific suggestions?
The party is really optimized (10th level), they killed Tyrgarun in 2 rounds with few damages:
1 cleric of Tempus with a custom prestige class (he's a tank)
1 druid with a lot of strong evocations
1 rogue/swashbuckler/swordsage
1 archer ranger with a custom prestige class
1 wizard well optimized

Moreover, the description of area 17 says that it's covered by Silence (given by unhallow). How can the PC listen to the noise at the top of the dome?
Further suggestions/hint about the room, to how to play/buff Azzarr, and the Aspect of tiamat will be good!

Thank you very much
