Iron Knight
Fey are some of the most annoying creatures to deal with. Luckily iron and a few tricks seem to work on them well enough. Iron Knights train in strength and endurance in order to wear their thick and menacing iron armor. They are moving walls of death that relentlessly pursue the Fey and end their fickle existence with prejudice. Iron Knights are only Witchers of the School of the Bear as other Witchers even empowered with mutagens would be helpless in their bulky iron armor.
Subclass Features
Iron Armor
Only Witchers of the School of the Bear are trained and capable of bearing the Iron Armor and maintaining it. You forge the Iron Armor using materials provided by the School of the Bear. The armor is a full suit of extra thick Plate Armor made of iron and embolized and stylized by you. You are proficient with the armor. Each plate of the armor is hollow and filled with salt, talismans, and symbols. The armor requires one hour of upkeep after combat or it loses its Anti-Fey feature. The Iron Armor has the following features
Anti-Fey: Any Fey that touches the armor or hits it with a melee attack takes 2D6 Necrotic damage. If the armor has not been maintained the damage is reduced to 1D4.
Deploy Shield/Sword: The armor is equipped with a built in shield and sword (Any non Two-Handed sword) that can be deployed or retracted as a free action. While deployed the shield or sword completely engulfs the hand not allowing you to hold anything else. The sword is a +1 weapon that deals an additional 1D8 Necrotic damage to Fey.
Fey Sense
You can sense the wind and see many signs that allow you to tell if a Fey is within 1 mile of you and track Fey for up to one week if you see direct signs of them.
Brute Strength
Wearing this armor is taxing in the extreme. Your efforts have trained you, you gain +1 STR (To a maximum of 20) and you gain one of the following Feats: Athlete, Heavy Armor Master, Mage Slayer, Shield Master, Slasher, or Tough.
Warded Armor
Your skills have progressed to the point where you can ward your armor with another layer of symbols. While wearing your armor you are Immune to the Charmed condition and Cursed items (With some DM discretion) cannot Attune to you. In addition the damage from your Anti-Fey feature is increased to 3D6 or 1D6 if the armor is not maintained.
Magic Reflection
The Iron Armor has absorbed magic from both Fey and arcane and has developed a resistance to it. You have advantage on saving throws against magic. If you are specifically targeted for a spell roll 1D20 on a 19-20 the spell is reflected on the caster as if you cast it using your Sign to hit and saving throw.
