Bonesculptor

This gory reimagining of a blacksmith makes armour, weapons and trinkets from the carcasses of slain great creatures. Through a combination of runic enhancements and harnessing the life essence of the slain beast, they are able to imbue their designs with potent magical energies.

I take no credit for this subclass. This is something made in the DND book "Dr. Dhrolins Dictionary of Dinosaurs". I've made this to use the book features in DND Beyond.

Level 3: Grim Harvest

You can harvest resources from slain creatures that you may use to craft items. Use the Creature Harvest Table for managing the resources harvested from a creature and how long it takes to harvest from that creature. When harvesting, the DM may decide how much, if any, of that resource you can harvest within the appropriate range of values. Your allies may assist you in harvesting. If at least two other humanoids assist you in harvesting, you may halve the harvest time taken for each creature you harvest from.

Level 3: Melder of Flesh and Bone

You gain proficiency in Heavy Armour, Leatherworker's tools, and Smith's tools if you did not have them already. You can craft armour, shields, and weapons from the parts of slain creatures. The Crafting Table opposite outlines the resource requirements for crafting these items, you must use Leatherworker's tools to craft armour and Smith's tools to craft weapons. You can craft a single item during a long rest. During this time, you may apply any other improvements to that item that your class would allow.

Body Knowlegde

You have advantage on Medicine checks, and you know the cantrip Spare the Dying in addition to your other cantrips.

Bonesculptor Spells

You always have certain spells prepared after you reach particular levels in this subclass, as shown in the Bonesculptor Spells list below. These spells don't count against the number of spells you can prepare.

Level 5: Butcher

You gain proficiency in one weapon type of your choosing. When making an attack roll, if you are attacking with a weapon that you crafted, you may use your Intelligence modifier instead of Strength or Dexterity for both the bonuses to hit and to damage.

Improved Crafting

You better understand the creation of items from flesh and bone. The items you craft using your Melder of Flesh and Bone ability become + I items of their respective type.

Construct of Flesh

During a long rest, you may craft a Construct of Flesh instead of an item. This requires 4 hide/skin, 4 bone/chitin, and any combination of 4 horns, feathers, scales, fangs, claws, or mandibles.

The Construct of Flesh is a friendly undead companion that obeys your commands. It is a Medium creature with the appearance of your choice (although usually fairly gruesome) and the statistics outlined in the Construct of Flesh stat block. You may only have a single Construct of Flesh at a time. If you create a second one, the first collapses into the components you used to create it.

In combat, the Construct of Flesh takes its turn immediately after yours. On your turn you may use bonus action to command it to attack, otherwise it may only move and Dodge on its turn. It may still use its reaction regardless of whether you commanded it to attack or not.

 

Level 9: Artisan Crafter

Your knowledge of your craft deepens to that of an experienced crafter. The items you craft using your Melder of Flesh and Bone ability become +2 items of their respective type.

Level 9: Improved Butcher

You gain proficiency in another weapon type of your choosing.

Improved Construct of Flesh

You may select a second ability for your Construct of Flesh from its initial list of abilities. The selected ability cannot be the same as the first one you picked. The Construct of Flesh also gains Multiattack, allowing two attacks.

Level 15: Master Crafter

Your creations are only rivalled by the works of master smiths. The items you craft using your Melder of Flesh and Bone ability become +3 items of their respective type.

Body Modification

Over the course of a long rest, you can incorporate one set of your crafted armour and up to two of your crafted weapons into your own flesh. They become a part of you and can only be removed if you choose to remove them over the course of a long rest. The weapons can be concealed within your body, and you may use a bonus action to draw them out.

Minion Master

The maximum hit points of your Construct of Flesh is increased by a further 60 hit points and its AC is increased by 2 (cumulative with the Robust ability if you selected it). You may select a second attack for your Construct of Flesh from its initial list of attacks. The selected attack cannot be the same as the first one you picked. All attacks made by your Construct of Flesh deal an additional 2d6 necrotic damage.
