Armorer's Insight

Your time working on armour has given you a keen eye for the defensive capabilities of those you come into contact with.

• As a bonus action you can make a Wisdom (Perception) check to glean the Armor Class of another creature. If you have attacked the creature in its current form in the last 30 seconds (5 rounds of combat) you can make this check with advantage. You can also make this check with advantage if the target is a humanoid wearing heavy or medium armour. To succeed the check, you must roll a total which is equal to or greater than the target's Armor Class. If you fail the check by 5 or less, the DM can let you know of this. If you roll a 20 on your roll before bonuses are applied, you learn the creature's Armor Class no matter if the bonuses would reach the target's Armor Class or not.
• As a reaction, when an ally within 5ft of you is hit with an attack, you can take defensive action for them and apply +1 to the target's Armor Class for the purposes of avoiding that attack. This feature can be used a number of times equal to your proficiency modifier and is recovered on a short rest.
• You gain a bonus of +1 to either your Strength or Wisdom, to a maximum of 20.
