Iron Hero
Prerequisite(s): 12th level
You have steeled yourself against grave threats. When all hope is lost, you stand tall against the storm. You gain the following benefits:
- You gain a +2 bonus to your armor class against creatures of CR greater than or equal to your level. You lose this benefit if you are charmed or frightened by the creature, or if you are incapacitated.
- You have advantage on attack rolls against a creature that has reduced one of your allies to 0 hit points in the last round.
- If a creature you can see within 60 feet takes a legendary action, you can use your reaction to try to interrupt the effect. Chose an ability score you have saving throw proficiency with and make an ability check with a DC equal to 10 plus 3 for each action the Legendary Action takes. On a success, the legendary action has no effect, but the actions are still spent. Once this ability successfully negates a legendary action, you can't use it again until you finish a short or long rest.
