Infernal Constitution Feat 5e: Guide for Players & DMs

Last Updated on January 22, 2023

This article breaks down the Infernal Constitution feat and why almost every Tiefling (no matter their build) should consider taking this feat. 

What Is the Infernal Constitution Feat in DnD 5e?

Infernal Constitution in 5e is only available to Tieflings. It grants Tieflings +1 to CON up to a max of 20 of course. It also grants you resistance to poison and cold damage as well as advantage on saving throws against being poisoned. 

Infernal Constitution Feat

Prerequisite: Tiefling

Fiendish blood runs strong in you, unlocking a resilience akin to that possessed by some fiends. You gain the following benefits:

  • Increase your Constitution score by 1 up to a maximum of 20.
  • You have resistance to cold damage and poison damage.
  • You have advantage on saving throws against being poisoned.

Now that you’ve seen and read what the feat does, let’s dive into it. 

So, is this feat worth taking on my Tiefling? 

Personally, I go with yes. The fact that this feat provides cold resistance and poison resistance is quite good with any class, especially if you’re doing some sort of a winter or snow campaign where cold damage is highly used.

Poison resistance is fairly common among certain races and even classes, but cold resistance is extremely valuable as cold damage is very popular.

There are over 20 different spells that do cold damage in 5e and six different spells that do poison damage, so having resistance to both is pretty good.

Of course, this depends on your campaign setting and the monsters/ enemies that you may be facing.

The +1 to Con is just good on nearly any class, especially if you’re a melee class such as a barbarian or fighter.

It’s also good on casters as well since the bonus to CON could potentially make it easier to make those concentration saves and improve your overall vitality, which is useful to any class/character.

To top it all off, having resistance to fire, cold, and poison damage is pretty good, and it forces your DM to throw different damage types at you. 

Infernal Constitution or Resilient? 

If you’ve done any research on this feat, you’ll find it often gets compared with Resilient, which allows you to add +1 to any stat you wish, and in addition to that, you gain proficiency in saving throws of the stat you increased.

This is a very good feat and is usable on any character, which makes it far more versatile and popular than Infernal Constitution.

With that said, you shouldn’t overlook Infernal Constitution as an option as it does provide very good damage resistances.

Saving throws are extremely important in DnD, and that’s why I personally give the edge to Resilient over Infernal Con for that simple reason.

Yes, the damage resistances are very good as are the advantage on saving throws should you get poisoned, but the ability to add +1 to ANY stat and gain saving throws in said stat is far more beneficial to nearly ANY character in DnD, no matter the campaign setting.

So yes, generally speaking, I say that Resilient is the better feat option between these two options. 

Is Infernal Constitution Worth Taking?

100% yes, no matter what, it’s worth it. I like taking Infernal Constitution on Tieflings!

Do you know if the DM is planning on throwing a lot of elemental/poison damage at you? If so, cold and poison resistances are nice to have.

Or do you know if the DM likes challenging combats? Then Resilient CON would be great for those concentration checks.

It’s a pretty well-rounded choice for Tieflings and definitely something you don’t want to pass up so quickly.

Infernal Constitution will give you a +4 to CON saves at max level, but I do see why some would take Resilient over this feat since it just gives you proficiency in essentially a saving throw of your choice.

However, you can’t deny the benefits of the damage resistances of Infernal Con. At the end of the day, I personally would highly consider taking this feat on my Tiefling no matter the class.

Plus, you can add some cool RP elements to your character since you acquired this feat, given its benefits and name. Ultimately it’s up to you.

Hopefully this article helped you out with your choice!
