[OOC] Return to the Rusty Rat

[DM Surranó]

Such questions can be decided on a case-by-case basis. It sounds harmless from game balance point of view but may be against the role. Consider a good cleric making a pact with a demonic demigod, maybe as a last resort for the greater benefit of good (in his own perspective at least; i.e. forced to take the pledge to save a village from destruction; or simply tricked into accepting a quest spell, etc.) that grants the power to summon fiendish creatures. Now, the demon would probably not serve the prayer if it were not to further his own cause.

Similar questions include whether a generic caster could learn a new evocation spell with a different element, e.g. frost ball or shock ball instead of fireball-- definitely as two new spells for purposes of spells known or spells scribed into spellbook. We can treat them as part of character's background that those are the self-developed "signature" spells of the character but using this uncontrolled may lead to a much wider arsenal of divine spells since divine casters know all the spells granted by the deity; not only a small set of selected once. (as opposed to arcane; even wizards are limited by the number of spellbooks they can carry and the funds sacrificed to buy new scrolls etc; but some spells may be particularly difficult to find)

So I encourage bringing up such questions in-situ and we can discuss there.
