I have an interest in the champion of Gwynharwyf’s ability to cast its spells while raging.
Furious Casting (Ex): Starting at 2nd level, a champion of Gwynharwyf can cast her champion spells even while raging. If she has another spellcasting class, she cannot cast spells from that class while raging, only the spells that she gains from her champion levels.
Unfortunately, the champion spell list is very lacking. (The spellcasting is the same as a cleric, but with no domains, very few spells per day, an extremely brief spell list, and a maximum of 4th-level spells.)
Thus, I would like to add spells to the spell list, and I’m seeking as complete a list as possible for ways to do that. Some are obvious-ish, such as getting a bonus domain, and others are less, such as the Races of the Wild prestige class skypledged, which gets access to a “divine spellpool” that it can pull cleric and druid spells from.
This kind of thing is widely discussed for sorcerers, but not so much for divine spellcasters since most of them are already casting whatever they like from an expansive list.
has to be compatible with furious casting, i.e. “champion spells.” Ruled to be concerned primarily with whether the spell is cast from a champion spell slot (rather than being strictly limited to the actual champion spell list or something).
has to be from a 3.5e source published by Wizards of the Coast (in a book, PDF, or web page doesn’t matter), or Dragon, Dungeon, or Dragon Compendium.
has to be available without recourse to epic rules.
does not have to be anything that a champion is likely or even plausibly going to qualify for. For instance, mage of the arcane order has “arcane” in the name, requires arcane spellcasting and advances arcane spellcasting, but the spellpool feature itself makes no requirement of being used only with arcane spellcasting.
does not have to concern itself with concerns of alignment or faith (e.g. the champion’s required CG alignment, Knight of Stars feat, or association with Gwynharwyf). There are ways around these, in theory, and in any event my game won’t necessarily be taking place in the official setting anyway.
