Create Servotron

5th level conjuration
Casting Time: 1 hour
Range: Touch
Components: V, M (mechanical parts for a 25 pound device, worth at least 1,000 gc)
Duration: see text
Classes: Artificer, Wizard (optional)

Casting this spell takes the form of you assembling the many intricate parts of a complicated mechanical device (the material component of the spell) while reciting repeated mystical incantations. Upon successfully casting the spell, the assembled parts becomes a crab-like mechanical construct using the Servotron stat block. Some values in the stat block are determined by your proficiency bonus (PB), and others are determined by the level of the spell slot used to cast this spell, as indicated.

The creature is an ally to you and your companions, under your control. In combat, it has its own initiative count and takes independent actions. The construct persists for 24 hours unless it is destroyed or the spell is dispelled. The material component can be recovered afterwards, but must be repaired and disassembled before being used to cast the spell again.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, use the higher level wherever the spell’s level appears in the stat block. Additionally, the construct persists for an additional 6 hours for every slot level above 5th.

Traits

Climbing: The servotron can climb and cling to difficult surfaces, including upside down on ceilings, without needing to make an ability check. Additionally, the servotron does not suffer a movement penalty when climbing.
Compartment: The servotron has a small 2 inch square compartment integrated within its belly. As a bonus action during its turn the servotron can open the compartment, use two of its multiple limbs to store or unstore an appropriately sized object within it, and close the compartment. This comparment is lined in the equivalent of a thin sheet of lead.
Multi-tool: Two of the servotron's various limbs contain retractable implements that function as theives' tools, and also as tinker's tools for the purposes of repairing items. The servotron gains their proficiency bonus on required checks for all such tasks.
Sync Up: As a bonus action during your turn, you can disable your own sight and hearing (effectively becoming blinded and deafened) until the start of your next turn. If you do and if the servotron is on the same plane of existence, you see and hear using the servotron's senses for the duration and you can silently issue the servotron a single command.

Actions

Acid Squirter (Recharge 6): The servotron spits acid in a line that is up to 15 ft. long and 5 ft. wide. Each creature and unattended object in the line are coated in acid. A creature may succeed on a Dexterity saving throw against DC 15 to avoid this. Each creature and object coated in acid takes 3d4 acid damage immediately and again at the start of each round for 1d4 rounds, or until a creature uses its action to scrape or wash the acid off.
Pincer: Melee Weapon Attack: +5 + PB to hit, reach 5 ft., one creature. Hit: 1d1 + 5 + the spell’s level piercing damage. This is considered to be magical for purposes of overcoming damage resistance.

Reactions

Spellnull (Recharge 6): The servotron can cast Counterspell as if using a 3rd level spell slot.
