I'm solely talking about basic magic resistance, not about enhancements by spells or items.1. Mages get +5 to the resistance of all six realms, not 5%.
2. Rawulfs magic divine resistance should be +15, not +5.
3. Realm skill value contributes to that realm resistance by skill/10 (rounded down). Example: Fire Magic is at 43, thus +4 fire resistance for that character.
4. Mages get a resistance bonus in the mental realm, depending on either INT or wizardry or both.
5. Priests get a resistance bonus in the divine realm, depending on either PIE or divinity or both.
6. No observations so far about bishops, alchemists and psionics.
7. It seems to me that hybrid classes don't get such a bonus, i.e. a valkyrie get no bonus in divine resistance.
8. Iron will increases the resistance of all six realms considerably. My party is not advanced enough for an exact formula, but it could be something like +5 when unlocking the skill and +1 every ten points of iron will.
Any comments or corrections?
