It's been a while so I don't recall how MR works in 2e. In 1e, it's adjusted by the level of the caster against an assumed level (8th level?). So if you have MR 50%, you have 55% against a 7th level caster and 45% against a 9th level caster (this is all assuming 8th level is the right baseline... it's in the MM).

Does 2e do this or is it a flat MR against everything, all levels?
It is based on 11th level not 8th.

(For further confustion, when the 'loths were introduced - later the yugoloths - they had MR ad different levels for different spell levels - each level over 1st having 5% less MR.)

Back to the OP and I would say it depends on what the divination spell is doing. I think for a locate X spell it makes sense to allow MR to apply, but for a see invisible it does not - one acts on the creature, one on the caster.
