Way of Ferrous Esotericism

The monks of the Way of Ferrous Esotericism hail from the Rusted Monastery in Acheron where they attempt to become one with the plane through deep meditation. Some of these monks have learned to channel their Ki into ferrous metals, effectively creating magnetic fields that enable them to manipulate said metals. An astonishing feat to be sure.

Rapid Oxidization

When you join the Way of Ferrous Esotericism at 3rd level, you gain proficiency with light and medium armor, and you gain the following ability:

Rapid Oxidization- As an action you touch a nonmagical metallic object that isn't being worn or carried and isn't made from adamantine, black iron, everbright, mithral, or stainless steel. A 1-inch-diameter cube of the object begins to oxidize at a rapid rate, transforming into powdered rust over the course of 10 minutes.

Ferrous Blades

Starting when you choose this tradition at 3rd level, you can momentarily manifest blades of shiny steel using powdered rust. Your unarmed strikes deal your choice of piercing or bludgeoning damage each time you hit. If you choose piercing, you create a ferrous blade that crumbles back into powdered rust immediately after the attack hits or misses. You can throw your ferrous blades up to 30 feet by momentarily conjuring and manipulating magnetic fields. You also gain the following abilities:

Controlled Oxidization. When you hit a creature that has eyes with one of your ferrous blades, you can expend 1 ki point to attempt to control how and when the blade crumbles back into powdered rust. The target must make a Dexterity saving throw against your monk save DC or become blinded until the end of your next turn.

Shredding Blades. When you hit a creature that has blood with one of your ferrous blades, you can expend 1 ki point to attempt to lodge the blade inside the target before it crumbles into powdered rust. The target must make a Constitution saving throw against your monk save DC or become poisoned for 1 minute.

Magnetic Deflection

Also starting at 3rd level, your Deflect Missiles feature is empowered by your control over magnetic fields.

When you deflect a metallic projectile using your Deflect Missiles, you reduce its damage by an additional amount equal to twice your Martial Arts damage, as shown in the Martial Arts column of the Monk table. If you reduce the damage to 0 on a metallic object, you can magnetically deflect the missile if it weighs no more than 1,000 pounds without needing to hold it and also without spending a ki point.

Ferromagnetism

At 6th level, you learn to extend fine ferromagnetic control over other objects. While wearing armor that contains metal, you can spend 1 ki point to cast the levitate spell, targeting only yourself. 

Additionally you gain the following ability

Magnetic Clinch - You attempt to move metallic objects by magically manipulating magnetic fields. When you this action each round for the duration, you can exert magnetic control on one metallic object weighing no more than 100 pounds that you can see within range and that isn’t being worn or carried, moving it up to 30 feet in any direction, but not beyond the range of this spell.

Ferrous Osmosis

Beginning at 11th level, you can manipulate magnetic fields to form almost any object from powdered rust. The resulting object is nonmagical, is metallic in nature, and can't have a value higher than 25 gp or be larger than 10 feet on a side. Forming an object in this manner takes 1 minute for every 5 gp the object is worth and requires your concentration (as though concentrating on a spell). You could, for example, create a 10-foot ladder, a shovel, a signet ring, or similar. If you would create an object such a piece of soap or a candle, you create an object of similar appearance, but its metallic nature would prevent it from working like a piece of soap or a candle. Once you have created an object, you can continue to concentrate to prevent it from crumbling back intro powdered rust. If you don't, the object crumbles after 10 minutes.

Ferromagnetic Potency

At 17th level your control over ferromagnetism increases. 

You can spend 5 ki points to cast the telekinesis spell, but you can target only target metallic objects and creatures that wear metallic armor or are poisoned by your Shredding Blades. You also gain the following ability:

Electromagnetic Polarization -  You may spend 1 minute to magnetize an object you touch that weighs no more than 5 pounds, is at least partially metallic, and that isn’t being worn or carried. You can choose for the object to be magnetized with positive or negative polarization. Objects of like polarization repel each other and objects of unlike polarization attract each other. 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood blocks two magnetized objects from repelling or attracting each other

Ferromagnetic Mastery

Starting at 17th level you can throw your ferrous blades up to 60 feet, and objects you create with your Ferrous Osmosis feature can be up to 30 feet on a side and have a value of up to 100 gp.
