Herculean Toughness (5e Feat)
From D&D Wiki
Prerequisites: Constitution 13 or higher
You have been through hellish training and trials making you exceedingly resilient. You may gain two of the following benefits when you choose this feat:
- Your hit point maximum increases by an amount equal to your level when you gain this feat. Whenever you gain a level thereafter, your hit point maximum increases by an additional 1 hit points.
- You gain proficiency in Constitution saving throws.
- When you take damage, you can use your reaction to roll a d4. Add your Constitution modifier to the number rolled and reduce the damage by that total. You may use this feature twice, and you regain all uses of this feature when you finish a short or long rest.
