I'm confused by Tristian and his whole Ecclesitheurge thing. If I've understood correctly:
- Ecclesitheurges get a primary domain and a secondary domain, Good and Healing respectively in Tristian's case
- They can prepare any spell from their primary domain's spell list in non-domain slots
- They can switch their secondary domain spell list for any other domain's spell list, as long as that domain is one of their deity's domains
From this it follows that Tristian can:
- Prepare any spell from the GOOD domain spell list in his non-domain spell slots
- Switch his HEALING domain spell list for another, such as the FIRE domain spell list
However, this is the GOOD domain spell list:
- Protection from Evil
- Protection from Evil, Communal
- Prayer
- Forced Repentance
- Burst of Glory
- Summon Monster VI
- Holy Word
- Holy Aura
- Summon Monster IX
Can you see the problem? All of these spells, if I'm not mistaken, are already Cleric spells. Therefore, the Ecclesitheurge's ability to prepare spells in non-domain slots is... utterly useless here.
And of course Tristian can obtain the FIRE domain spell list, but he cannot shove those spells into all of his non-domain spell slots because they are from his
secondary domain. At least, he
shouldn't be able to. Can he?
