Flash of Genius
When you or another creature you can see within 30 feet of you makes an ability check or a saving throw, you can use your reaction to add +5 to the roll.
Each of the armor’s gauntlets counts as a simple melee weapon while you aren’t holding anything in it, and it deals 1d8 thunder damage on a hit. A creature hit by the gauntlet has disadvantage on attack rolls against targets other than you until the start of your next turn, as the armor magically emits a distracting pulse when the creature attacks someone else.
As a bonus action, you can gain 8 temporary hit points, replacing any temporary hit points you already have.
