Resolute (feat)

Whether through intentional training or pure luck, you always seem to cling to consciousness even when you are at death's door. You gain the following benefits:

• Increase your Constitution score by 1, if doing so does not exceed your maximum.
• When you are reduced from over half your maximum heart points to 0 heart points, but not killed outright, you are reduced to 1 point instead, and are immune to damage from nonmagical weapon attacks until the start of your next turn. You must complete a short or long rest before this feature can be used again.
• When you finish a long rest, you gain temporary heart points equal to your your Constitution modifier plus your proficiency bonus.
