Does energy resistance stack with Endure Elements?

[Nareau]

I'm pretty certain it does, but I just want to double check. I'm thinking of taking a level in Elemental Savant (of the aqueous persuasion), and being safe from the first 10 points of cold damage would be kinda cool...

No, they don't stack.

 

[Nareau]

OK...

Could you explain why not? Thanks.

The Elemental Savant class grants you Resistance (5) against an elemental type.

DMG, page 81, Resistance to Energy, 5th bullet point: "This resistance does not stack with the resistance that a spell such as endure elements, might provide."
