Metallurgist

Most magic deals primarily with natural elements throughout the world, and alters those elements to fit a need. The School of Metallurgy, however, focuses on metals and ores. To shape both a natural and man-made medium takes time and great practice, but it is all the more rewarding.

Steel Blessing

At 3rd level when you join the School of Metallurgy, you can bend metals to your will, and infuse flesh with steel.

As a bonus action, you may enshroud yourself or a willing creature you can see within 30 feet of you with the essence of metal. When you grant this Steel Blessing, you or the creature gain 4 temporary hit points for each Wizard level you have. A creature (including you) that has temporary hit points this way gains the following:

• The creature deals additional force damage with spell attacks and weapon attacks equal to your Intelligence modifier
• The creature gains a bonus +2 points to their Armor Class

The Blessing lasts for 10 minutes, you or the creature dismiss it as a bonus action, or you or the creature lose all temporary hit points, whichever comes first. Only one creature may have the Steel Blessing at a time, and you may grant it a number of times equal to your Proficiency bonus per long rest.

Mechanist Familiars

A wizard is nothing without their familiar, and at 3rd level you have worked your metallic talents into even this aspect of your studies. You learn the find familiar spell, can cast it as a ritual, and it is thereafter always prepared.

When you cast the spell, you can choose one of the normal forms for your familiar, but their creature type becomes Construct or you may choose one of the following special forms: scarecrow, metal wasp, tin soldier, or flying sword.

Additionally, as a bonus action on your turn, you may command your familiar to make one attack with its reaction.

Metal Shaper

At 6th level, metal is shaped before you like ink on a canvas, shifting and changing to your every whim.  As a bonus action, you can touch a nonmagical metal object of size Medium or smaller that is not being worn or held, and transform it into another object of the same general size.

If you create an arcane focus (such as a wand), a weapon, or armor this way, you may don or equip the armor, focus, or weapon as part of the same bonus action. If you create an arcane focus, a weapon, or armor for another creature this way, the creature may use their reaction to don or equip the armor, focus, or weapon.

Objects created in this way revert to their previous form when you take a long rest. You may alter metal objects this way a number of times equal to your Proficiency bonus per long rest, and regain one use each short rest.

Reconstruct

At 10th level, you have learned to repair metal much the same way a cleric can heal flesh. Whenever you cast a spell of 1st level or higher, you may grant yourself or another creature temporary hit points equal to 3 plus the spell's level.

If the creature already has temporary hit points as a result of the Steel Blessing feature, you add these temporary hit points to the overall total.

Tempered

By 14th level, you are able to take the metals that you have come so accustomed to using and greatly strengthen them with your magic. Your limbs can no longer be severed from your body and your bones can no longer be broken. Additionally, when a creature (including you) has temporary hit points as a result of your Steel Blessing feature, they gain the following additional benefits:

• Resistance to bludgeoning, slashing, and piercing damage from non-adamantine weapons
• Any critical hit against you/the creature becomes a normal hit instead

You may now also grant Steel Blessing to two creatures at once instead of only one.
