Dumathoin cleric prestige class

[Andion Isurand]

Before you proceed any further, I would look at Races of Faerûn for additional insights into the "Urdinnir" ( <--- spelling? )......

.....Dumathoin's favored dwarves....

( its true that they were originally sheild dwarves before the deity's involvement)

Aside from the extended flavor text on them and their deity.... there are a few really cool "crunchy bits" that might inspire your PrC's mechanics.

 

[Mjollnir]

I still haven't got "Races of Faerûn". On the rest, could you be more specific, please?
