Necro Golemmancy

The School of Necro Goelmmancy explores the cosmic forces of life, death, and undeath. As you focus your studies in this tradition, you learn to manipulate the energy that animates all living things. As you progress, you learn to sap the life force from a creature as your magic destroys its body, transforming that vital energy into magical power you can manipulate. And instead of spending your studies on raising an army of the undead you decied to create just one ultimate DeathKnight 

Most people see necromancers as menacing, or even villainous, due to the close association with death. Not all necromancers are evil, but the forces they manipulate are considered taboo by many societies.

Necromancy Savant

Beginning when you select this school at 2nd level, the gold and time you must spend to copy a necromancy spell into your spellbook is halved.

Grim Harvest

At 2nd level, you gain the ability to reap life energy from creatures you kill with your spells. Once per turn when you kill one or more creatures with a spell of 1st level or higher, you regain hit points equal to twice the spell’s level, or three times its level if the spell belongs to the School of Necromancy. You don’t gain this benefit for killing constructs or undead.

Golemmancy

Starting at 2nd level you gain the ability to create the golems core.

The golems core can only support a medium humanoid build. The golem health is depicted as temporary health and mending can only heal  so much. The golem is immune to psychic, poison, paralysis, and health draining abilities. The golem is resistant to necrotic but is vulnerable to radiant.

When creating the core, you must spend 8 hours to create it and if a core already exists the old one disappears.

You can spend 1 hour summoning the core to your location (if it is not destroyed). All of the body parts attached do not follow.

Grafting

You learn at 2nd level how to graft bodyparts to your golems core (This is what makes up their stat block and Special abilities)( use the stats and abilities of the corresponding part and creature that has been grafted). When incorporating body parts onto the core the rate at when the flesh decays is reduced

you may not be able to use the full potential of the creature parts

Head:  Gains their Sight and head abilities if the creature had one (Like bite attack)

Chest: Gains the AC of the creature (without armor) gains 1/3 of the creatures health (gain 2/3 if the body still has enough flesh) and any of the abilities the creature had (Like Breath Attack) use the body's Constitution stat

Left Leg: Gains half the running movement and any of the leg abilities use half of the abilities unless both legs have the same abilities (Like feline agility would only increase the movement by half) Use half of the legs dexterity stat

Right Leg: Gains half the running movement and any of the leg abilities use half of the abilities unless both legs have the same abilities. Use half of the legs dexterity stat

Left Arm: Gains the strength and any special attack (like claw) Use half of the arms strength stat

Right Arm: Gains the strength and any special attack. Use half of the arms strength stat

Wings: gains flight movement (only if the wings still have enough flesh or if the creature flew via magical means)

Tail: Gain tail abilities the creature had

 

Golem Specialist

Starting at 6th level you gain the ability to focus on how you want you golem to be in battle

Armorist

You decided you wanted the golem to become a tank you learned how to incorporate armor into your bones allowing the golem to wear armor that fits 

The golem gains the feature that the armor would give but you need to use the armor to actually make it destroying the armor in the process

Chimera

you start making your golem in more of a monstrosity this allows each part of the body (Besides chest) to be replaced with any other body part (like 4 legs) the golem is now considered a monstrosity and you gain a extra head slot

(Keep in mind unless the body part has a attack ability they cant attack or see if you don't have a part that can)

Core Ability

You decided that upgrading the core rather than the body would be a better choice allowing the golem to be further enhanced

Choosing this option again allows you to choose another feature

Health: +30 hp whenever you graft a new chest

Agile: +20 to all possible forms of movement and ignore difficult terrain

Strong: +2 to all strength

Hard hitter: can attack an additional time

Preserver: Preserves the flesh for even longer

 

Giants Might

You start making you golem bigger allowing you to increase the size class by 1 and making it that you gain 2/3s of the creatures health and full health if their is enough flesh the golem now adds 1d6 to all attacks using strength

taking this feature again allows you to increase the size class by another 1 and adds a additional 1d6 to attacks

OverClock

you start forcing more parts onto the golem so you can reap the benifits from more than 1 creature

you gain 2 more slots between arms and legs or a mix( this can take up the same space as the other arms if you dont want 4 arms)

taking this feature again gains you 2 more slots

Runes

You learn how to inscribe spells onto the golems bones allowing them to cast the spell. when you inscribe a spell you lose that spell slot until the golem no longer has the inscription.

Cantrips can be used and the spell can be cast again whenever you would regain that spell

the golem uses your mental modifier to cast the spells

Taking this feature again gives the golem resistance to magical effects

Soul sapper

When the golem hits he regains half the amount of that damage

Yoink

Your proficiency in grafting parts to the golem increase allowing you to possibly obtain class specific skills that the body part may have had (Like a barbarians rage)

Inured to Undeath

Beginning at 10th level, you have resistance to necrotic damage, and your hit point maximum can’t be reduced. You have spent so much time dealing with undead and the forces that animate them that you have become inured to some of their worst effects.

One man army

You gain the ability to create a second core
