Hmm! Gives me a lot to think about. I have up until now not used the RR bonuses for Hybrids at all. With the motivation thinking that the combination of schools makes their spells unique. Was hoping for a more official ruling though.
Using the RMSS character sheets as the basis, the modifiers are cumulative.
I do use the RMSS character sheet and I can't understand where you get that the modifiers are cumulative. But I'll take your word for it and considering that only get two of their Stat bonus against hybrid spells (not counting Arcane) you could say the additional Racial RR bonus would account for the missing stat bonus. But I do feel that in this case the bonuses would get a bit to high if combined.
Another way to handle this is to consider it similar to how the Hybrids handle their PP progression. That is using the lesser of the bonuses that applies. Or you can go the other way and use the better of the bonuses that applies.
I guess it comes down to what I prefer.
But the options so far is:
- They don't get any Racial RRs at all against the Hybrid spells. The Hybrid combination is considered a new realm of magic.
- Use the lesser of the Racial bonus that applies. Similar to how Hybrids handle their PP progression.
- Use the higher of the Racial bonus that applies.
- Use the average of the Racial bonuses that applies. Makes most sense for me and similar to how Hybrids calculate their Stat bonus.
- Add the Racial bonuses that applies together. As Peter Mork suggested.
Gah! Hate to take these decisions when all the pros and cons cancel each other out!
