Magic Resist to Spell Resist.

[Tyris Harmon]

Anyone know how the conversion for Magic Resistance to Spell Resistance was/is done? I have a conversion doc for monsters but it doesn't even mention that. Can't seem to find it anywhere else.

11 + 1 per 5%

So a creature with a 80% spell resistance would be SR 27

A 1st edition 10th level caster would need to roll a 17 or higher to affect a creature with 80% spell resistance

So converting it to 3.5 they need the same roll so a 10th level caster with a 17 roll would be SR 27.

So Base 11 plus 1 point per 5%.
