D&D 5E [5e] Hellish Resistance (Tiefling Racial) & Elemental Affinity (Fire)

[CriticalBurrito]

I (DM) have a player in my campaign that has rolled a Tiefling Draconic Sorcerer (Red Dragon). We just leveled up to level 6, so the sorcerer gains Elemental Affinity, granting the ability to expend one Sorcery Point ("SP") after casting a fire spell in order to gain fire resistance for 1 hour. Now, the tiefling racial "Hellish Resistance" grants fire resistance as well.

As a DM, I like to let people make tweaks or substitutions where classes, races, feats or backgrounds overlap. In this instance, I wanted to tweak the Elemental Affinity ability to be both thematic and also provide a meaningful use for the part of Elemental Affinity that allows you to spend some SP to gain... something.

I'd prefer to keep this in Occam's Razor territory as well. The simplest solution is the best solution.

Things I've come up with so far:

1. Cold Resistance - Since you are a fire caster, kinda makes sense that you could harness all that spiciness to shrug off the cold.
2. Fire Immunity - This is the natural progression from Fire Resistance, but feels way to powerful without reworking the action economy/concentration/resource cost/#uses per SR or LR.
3. Fire Shield - You can bring up a shield that allows you to mitigate a certain amount of fire damage before disappearing. This is like immunity, but for a limited amount of damage. But who would this work? How much damage? Does it scale with level and/or sorcery points expended?

Any other thoughts or recommendations?

Make it a flat reduction like heavy armor master. 3 fire damage reduced before resistance from every individual source.

Advantage on saves vs fire damage?

Go with cold. Simple and easy. I agree fire immunity is too good, too easy to abuse if your not careful.

I would go with something like:

Flames of Rauorlogskor. When you spend a Sorcery Point, you gain an additional layer of protection against flames and fire. For the next minute, whenever you make a saving throw against a fire effect, you take half damage on a failed save, and no damage on a successful one.

Naturally, this on top of his Tiefling ability, so he is looking at 1/4 damage from a failed save on a fireball, or none if he successfully makes the save; while the feature is engaged.
