So, every time some feature, item or whatever allows a player character to have Magic Resistance, people seem to go crazy about it. It happened when the Yuan-Ti was released as a playable race in VGM, it happened recently when the Satyr was announced for Theros, and it happened around here with the possibility of allowing a player to get a pseudodragon as familiar.
I am asking because honestly I have never played with an Yuan-Ti, but in most of the campaigns I DM or play, I don’t see Magic Resistance showing up a lot or helping the players a lot. It is certainly a strong feature for monsters since parties will often contain spellcasters, but most creatures do not have magical effects or anything. So, the question is straight forward: is allowing a player character to get Magic Resistance as broken as I have seen people assume? Am I missing something?
Magic Resistance. You have advantage on saving throws against spells and other magical effects.
