Metal Magus

At 6th level, you can alter mundane metals to a phenomenal degree. Your shape metal* spell can affect Medium objects. Additionally, as an action, you can touch a metal object and apply one of the following effects:

• You can increase the armor class of armor or a shield by 1.
• You can increase one damage die on a weapon by one size, up to a maximum of a d12.
• You can grant a weapon the reach property.
• You can apply any effect of the shape metal* spell.

This effect lasts for 8 hours, until you complete a long rest, or until you use this ability again.

Quicksilver Boon

At 10th level, you can create metallic blessings for your allies at a moment's notice. As a reaction after a creature you can see within 30 feet is hit with an attack but before damage is rolled, you can summon a quicksilver coating of protection. They gain resistance to bludgeoning, piercing, and slashing damage from that attack.

You can use this ability a number of times equal to your Intelligence modifier, regaining all uses after completing a long rest. You regain 1 spent use when you use your Arcane Recovery feature.

Scholar of Steel

At 14th level, your mastery of metal magic is unsurpassed. Your shape metal* spell can affect Large objects, and you can use it to manipulate complex objects (such as opening a lock or repairing a machine). If the object has an associated DC (for example, picking a lock), you make a spell attack roll against the DC.

Iron Will

Also at 14th level, you have advantage on Wisdom and Constitution saving throws as long as your Iron Shell is active.

You twist illusions around a melee weapon you are holding. When you cast the spell, and on each subsequent turn for the duration as a bonus action, you can create feinting blows with the illusory copies of your blade, distracting your target and giving you advantage on the next weapon attack against that target before the end of your turn. The spell ends early if you let go of the weapon you cast it on.

As an action, a creature that can see you can make an Intelligence (Investigation) check against your spell save DC. On success, you no longer gain advantage from using the illusionary blades when making a feint against that creature, rendering the spell impotent against that creature.

Alternately, you can use your action to attempt to impale one creature within 15 feet. The target must make a Dexterity saving throw. On a failure, they take 6d8 fire and 6d8 piercing damage.
