Patryn of Elvenshae said:Except that, in many cases, clerics are required to have deities. It is a fairly common house rule, in addition to being the RAW for the Forgotten Realms Campaign Setting and, similarly, for the Eberron Campaign Setting (where non-deity clerics draw their power from the Ring of Siberys).
Not true in Eberron (see page 35 of the Setting book "You may also decide that character has no deity but channels from the Spiritual Remnants of the Dragon Above."
In Races of Eberron it also talks about the special aspects of Warforged and Kalashtar when it comes to religion and divinity.
It is true in FR.
d20 Ravenloft – pg 50 talks about how clerics from other worlds still receive their deity’s favor. Since that was the example given and it has a game mechanic in place – I’d use it. They basically still receive all benefits but feel deserted and often times have crisis of faith to deal with.
Since this wasn’t a house-rules question – I try to default to the non-house rules issues. It was also not specified it was FR so I didn’t have the setting specific information to use.
