Construct Bone Golem

This spell makes a bone golem construct at an empty space that you can see within 10ft of you that lives to serve you and will obey your every command given to it to the best of its abilities until the 24 hour duration of the spell runs out or it dies, and the golem explodes into a rain of shrapnel which gets impaled into every creature within 30ft of it, dealing 4d8 piercing damage to every creature within said range that does not succeed on a dexterity saving throw using the caster's save DC. You can only have one golem summoned at a time, and this restriction is shared between all golem summoning spells.

On each of your turns, you can use a bonus action to mentally command the golem if it is within 60ft of you. You decide what action the golem will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the golem only defends itself against hostile creatures. Once given an order, the golem continues to follow it until its task is complete. You may also use a bonus action to dismiss it if desired, thus getting rid of it without the explosion.

Additionally, you may use a bonus action on your turn to touch the golem and be pulled inside of it like a large suit of automated armor, giving you full cover by making any attacks that target you, target it instead, and giving you its speed, making you always overlap its space while inside of it, while also necromantically connecting yourself to the golem, thus resetting and pausing the 24 hour duration timer on the golem, giving you the golem's tremorsense but not being able to see out of it otherwise. It can mentally communicate with you while you are inside of it, you can command it with a free action while inside it as well, and any spells that you cast on yourself are cast on the golem as well while inside of it. You may leave the suit with a bonus action, getting rid of the full cover and speed again in doing so, and if the golem dies while inside of it then you are shunted out of it without being hurt by the shrapnel explosion.
