Create Bone Construct

Order undead creatures of your choosing, that are also under your control to form a bone construct. The creatures die and their essence turning to bones, that connect together and slowly take a rough shape of a humanoid, becoming a bone construct. It's HP is the maximum HP of all the creatures sacrificed divided by 2. Each of it's ability scores is the highest score between all creatures sacrificed. If this spell isn't used on the construct every 24 hours or the construct is dispelled, it crumbles into an inanimate pile of bones, that can be again turned into a construct of the same level it was before crumbling by casting this spell on it. All Levels of constructs have a resistance to necrotic damage and an AC of 13, except the 7th level, which has an AC of 17. The construct can squeeze through any passageway by turning itself into an animated pile of bones, however it can't use any of it's physical attacks in that state. You can control 1 bone construct at level 7, two at level 14 and 3 at level 20.

Level 1 - Bone Construct, small construct

If 3 to 4 creatures are sacrificed, the spell makes a Bone Golemling, can only do basic attacks, dealing 1 + its STR modifier, does not have a mind of it's own and cannot read or speak.

Level 2 - Lesser Bone Golem, medium construct

If 5 to 11 creatures are sacrificed, the spell makes a Lesser Bone Golem, that can use nearby objects as improvised weapons. It also gains all the abilities of it's lower level.

Level 3 - Bone Golem, large construct

if 12 to 18 creatures are sacrificed, the spell makes a Bone Golem, that has two heads, is sentient, but will still obey commands. It also gains an ability to extend or even shoot out spiked bones from its body. The body spikes do 1d8 piercing damage to creatures 2 ft away from it and ranged spikes deal 1d6 piercing damage. For every of the construct's levels higher than 3, these attacks deal an additional die of damage. Each ranged shot consumes 1 HP of the the Bone Golem. It also gains all the abilities of it's lower levels.

Level 4 - Greater Bone Golem, large construct

if 19 to 34 creatures are sacrificed, the spell makes a Greater Bone Golem, that is able to speak any language the caster can, although only on a basic level. The Greater Bone Golem can cast Ray of Sickness 3 times a day without the use of components. It also gains all the abilities of it's lower levels.

Level 5 - Bone Monolith, huge construct

if 35 to 99 creatures are sacrificed, the spell makes a Bone Monolith, that gains its own free mind, becoming difficult to control, therefore preventing the caster from having more than 1 of any bone construct, the other bone constructs under the caster's control crumbling as if dispelled. As a bonus action it can consume undead creatures that are 5ft away from it either restoring its own health by the the consumed creature's current HP if it's hurt or adding the creature to its body if it's at maximum health. If a creature is added to the Monolith's body, It is counted as a creature sacrificed, therefore influencing the Monolith's HP, ability scores and sacrifice count. Undead that are targeted by this ability are given a free action before they are consumed. The Monolith will automatically consume nearby undead to heal itself if it's at 15% of it's maximum HP, even against the caster's will. it also gains the ability to understand even the most complex commands and read and write any language the caster can. The Bone Monolith also gains all the abilities of it's lower levels.

Level 6 - Bone Leviathan, huge construct

if 100 to 199 creatures are sacrificed or consumed, the spell makes a Bone Leviathan, that has a three heads and four arms. As an action it can attack with all of it's arms, each doing 1d8 + it's STR modifier bludgeoning damage on hit. On a miss, any of the attacks cause the ground to shake in a 5ft wide area where it finally lands and on a failed DC 15 DEX saving throw anyone in that area is incapacitated for 1 round. Once a turn the Bone Leviathan can choose to empower one of the four attacks by extending sharp bones from its fist, adding an additional 1d6 piercing damage to it. If a spiked attack misses, in addition to the normal effects, the spikes on the Bone Leviathan's fists break, dealing 2 damage to itself and rise out of the ground, occupying a 5 ft square around where they landed, remaining there until dispelled or broken with a successful DC 13 STR check. On a failed DC 15 DEX saving throw the target (if still located in the square occupied by the spikes) takes 1d8 piercing damage. The Bone Leviathan also gains all the abilities of it's lower levels.

Level 7 - Bone Monarch, gargantuan construct

if 200 or more creatures are sacrificed or consumed, the spell creates a Bone Monarch, that has bony wings, a flying speed of 15ft and bends the rules of reality, but is highly unstable. Unless it eats an undead creature or any form of living creature's remains every 5 minutes after being summoned, it explodes violently, sending spiked bones in all directions and creates a 30ft wide blood-red colored cloud centered on the dead construct, that deals 4d8 necrotic damage to any creature inside, applying poisoned and settles in 3 turns. If the monarch feels death approaching and there are no undead or remains to consume nearby, it may go berserk and massacre anyone in sight, including it's allies and the caster, although it prefers to target other creatures first. as an action the Bone Monarch can cast Animate Dead and Create Undead without the use of any components and at will. 5 times per day the Bone monarch can put any undead creature under it's control as a bonus action for the duration of a day or until dispelled. If the creature's INT score is higher than 15, it only comes under the monarch's control if it fails a CHA saving throw against the Monarch's CHA check. The number of uses of this ability only decreases when it succeeds. For each 75 undead or remains the Monarch consumes, it can choose to grow an additional arm, that adds additional attacks to Bone Leviathan's multi-attack action, an additional leg, gaining a bonus 5ft walking speed or an additional wing, gaining a bonus 5ft flying speed. All the damage dealt by the bone Monarch counts as magical. The Bone Monarch also gains all the abilities of it's lower levels.
