Shield master doesn't work against fireballs, it only works against single-target spells.
As for tieflings... well, a wizard with the elemental adept feat can just ignore fire resistance (and ensures that the minimum damage on the fireball is bumped to 16). Or a Scribes wizard can just have Spirit Shroud in their spellbook, cast necroball, and be done with it. Or a sorcerer with transmuted spell can use another elemental type too, though for them it costs SPs.
You sure shield master doesnt work on fireball? The AC bonus to DEX save doesnt apply, but taking no damage on a succesful save should still apply, no?
You're right, though they still have to make the save first. I recommend pairing it with a Ring of Evasion in that case. Though both the ring and the shield master feat use your reaction so even that is less than ideal.
