What Is the Boon of Fortitude Feat in 5e?

The higher you level in D&D, the more deadlier foes you’ll face. The Boon of Fortitude ensures you can take hits and keep standing. This Epic Boon feat grants a significant permanent health boost and improves your healing efficiency, making it a fantastic choice for frontliners and anyone who wants to stay in the fight longer.

How Does Boon of Fortitude Work?

Boon of Fortitude is one of the Epic Boons found in the 2024 Player’s Handbook. Unlike regular feats, Epic Boons are only available to characters who reach level 19, making them a capstone reward for the most powerful adventurers.

When you take the Boon of Fortitude, you gain the following benefits:

Ability Score Increase: Increase one ability score of your choice by 1, to a maximum of 30. This increase is useful, but the real power of the boon comes from its ability to influence fate. The maximum of 30 is (typically) impossible to hit if you’ll just be playing to level 20. Instead, it’s meant to be a reward for gaining levels beyond level 20 as described on page 46 of the 2024 Player’s Handbook.
Fortified Health: Your Hit Point maximum increases by 40. Additionally, whenever you regain Hit Points, you heal extra HP equal to your Constitution modifier. This bonus applies once per turn, significantly improving your sustainability in battle.

How to Get the Boon of Fortitude Feat

Any class can pick up the Boon of Fortitude feat when they reach level 19 and gain the Epic Boon class feature.

Is Boon of Fortitude Good?

In our 5e Feats Tier List, Boon of Fortitude was given a B Tier rating, making it a niche feat that can improve some builds in D&D 5e.

This feat dramatically increases your survivability, making it one of the best options for characters who take damage regularly. The raw HP boost alone is fantastic, but the added healing benefit makes it even stronger for classes that rely on self-healing or receive frequent healing from allies.

Perfect for Frontline Survivability

If you’re a Barbarian, Fighter, or Paladin, this boon turns you into an absolute wall of health. The extra healing also synergizes well with classes that have high Constitution or action-economy-efficient healing effects, like Second Wind or Lay on Hands (now that it’s a Bonus Action).

Combined with the Tough feat, you can have an extra 80 Hit Points by level 20!

Which 5e Classes Make the Most of Boon of Fortitude?

The color code below has been implemented to help you identify, at a glance, how good the Boon of Fortitude 5e feat is for a specific class/subclass.

Red: Weak, unlikely to contribute to your build

Orange: Situationally good, but below average

Green: A solid choice

Blue: A great option worth considering

Sky Blue: One of the best choices for optimization

Artificer: A solid pick for Artificers, particularly Armorers and Battle Smiths, who can end up on the frontlines.

Barbarian: One of the best feats for Barbarians. The raw HP boost stacks well with the Resistances offered by Rage, and the extra healing helps keep you in the fight.

Bard: Bards aren’t known for their durability, and it's not particularly important as they won't be in the thick of the battle. But, if you’re a College of Valor or Swords Bard, this can help you survive in melee combat.

Cleric: Clerics love more HP, so they don't have to spend resources healing themselves as often. Plus, when they do have to give themselves a heal, it'll be more effective.

Druid: Druids that aren't focused on Wild Shape don't particularly need increased durability as they won't be in the thick of the battle. But, if you’re a Circle of the Moon Druid, this can help you stay in Wild Shape when combat heats up because your Wild Shape no longer takes over your baseline Hit Points in the 2024 rules.

Fighter: Fighters already have great durability, but this boon takes it to the next level, making you even harder to kill. This also combos with your Second Wind by allowing you to add your Constitution modifier in addition to the Hit Points you gain.

Monk: For a class with notorious survivability issues, extra Hit Points are always a good thing.

Paladin: More Hit Points means you'll stay up longer, laying down smites and buffing party members with your auras. Plus, it's easier to keep you up thanks to being able to add your Constitution modifier to any healing resources.

Ranger: Rangers benefit from the extra HP but those that focus on ranged combat may prefer a more offensive Epic Boon, like the Boon of Combat Prowess.

Rogue: While it's not the most exciting pick for Rogues, the extra HP can help mitigate their low durability.

Sorcerer: More HP is always good, but there are more exciting Epic Boon options.

Warlock: Warlocks benefit from the extra health, but may prefer boons that enhance their spell casting.

Wizard: More HP is always good, but there are more exciting Epic Boon options.
