Giant's Endurance

You are the descendent of Giants and thus you are hardy and pain is little more than a test , granting you the following benefits:

• When you take this feat, when rolling for health this level you may add your Constitution modifier to your health total again.
• Your Stone's Endurance racial ability becomes Giant's Endurance and reduces incoming damage by 2d12 + your Constitution Modifier instead.
• If your Giant's Endurance ability reduces the damage past the total, you may add the remainder to your total max hit points. This effect lasts 10 minutes.
• Gain access to a new ability called Giant's Bastion and it functions like this. Once per long rest as a reaction, you may add your Constitution Modifier to your AC until the start of your next turn. The trigger for this reaction is if you are targeted by an attack.
