Smith

This subclass is great for having some good old fun as a sort of fire-y Thor. Their brute strength can carry them alone through a fight and their resistance to the fiery heat of the forge can carry them through volcanoes and dragons alike.

Hammer Expertise

You gain Expertise with any Hammer (Light Hammers, War Hammers, etc.)

Quick Fix

You gain Proficiency with the Smith's tools and you also get Smith's Tools for your practices in it. You also know the Create Bonfire and Mold Earth cantrips. When you cast Mold Earth, you can use it to create an oven that you can cast Create Bonfire into and get a forge that you can make repairs and forge in. When repairing or creating an item, you make an Intelligence check against a certain DC to repair or create said item.

Repair - DC - Time

Small Repair (crack, dent, bend) - 5 - 30 min-1 hour

Medium Repair (two small parts that were once together, something of the like) - 10 - 30 min-1 hour

Big Repair (recreating a part, big break, something big) - 15 - 1 hour +

Fires Of The Forge

You can cast Wall of Fire once without expending a spell slot.

Anvil Strike

As your Action, you can strike the ground in front of you causing everyone within a 10 foot radius except you make a Strength Saving Throw against (DC 8 + proficiency bonus + Strength mod) or be knocked prone. If you knock a creature prone within 5 feet of you, you can make one attack against them as a bonus action. When you strike the ground in this way, the booming sound of a hammer hitting an anvil eminates out to 300 feet away form the point of impact.

Heat Sustainability

You have resistance to fire damage from radiant heat (the heat of a volcano or giant fireplace)

Anvil Strike Upgrade

Your Anvil Strike quake radius expnds to 25 feet and deals 3d10 thunder damage to anyone in a 10 foot radius that can hear.

Anvil Strike Upgrade

The quake radius goes out to 50 feet and the strike deals 5d10 fire damage against all creatures within 10 feet of the impact if they do not make a Dexterity save against (DC 8 + proficiency bonus + Str mod) as pillars of flame burst forth from the ground.
