"Concept for a Maintenance bot that keeps things running even though there are no Mechanics

----------
UPDATE:
I have finished the Bot, you can see some of it's renders here >> https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2965627561

Name: C14RK (Clark)
Class 14 Repair unit model K

Tools:
Dual Arc Welder
Nailgun/Compressed Air Gun
Flamethrower

Health: 60

Attacks:
Welder -- melee // Stun, Weld pinch
Nailgun -- ranged // Nails, Heated Nails | pushback // Airblast
Flamethrower -- close-range // Burn | Nails Heatup

Damage:
Airblast -- 5
Stun -- 10
Nail -- 30
Weld Pinch -- 35
Heated Nail -- 60
Flamethrower -- 30/s, 30 afterburn at 5/s

Special:
Stun -- You move and perform actions 30% slower
Heated Nail -- After sticking into terrain acts as chip damage, avoid touching it, cools down after some time
Airblast -- Pushes entities 4m back

Strategies:
Hide behind concrete -- Bot can cut and shoot nails through thin Metal and Wood walls/weak material walls
Strafe -- Nails are fast projectiles
Keep distance -- Flamethrower is devastating and Stun can leave you vulnerable to other bots
Bring lots of ammo -- If you attempt to melee the Bot it will keep pushing you away with Airblast and Weld Pinch/Stun if you get too close
Use downtime -- Bot needs time to heat up nails/reload
Splash the bot with water -- Water reduces Airblast effect, nails fly slower and cools down Nail Mag if heated up
Shoot the Gas Tank -- If you manage to get behind the Bot you can shoot the Gas Tank to significantly lower it's health and disable Flamethrower, but it also means you won't get the tank as a drop

Drops:
Broken Toolgun -- 5%
Broken Welder -- 10%
Gas Tank -- 10%
Welding Battery -- 20%
Nailgun Magazine -- 25%
Battery -- 40%

Side Notes: didn't think of Nail Mag and forgot about rotary wrist part of the welder when drawing, oops"
