Overview

Molten Ball Blaster is a hyper-efficient build that utilizes an arsenal of Tools to create powerful looping Charge triggers.

It's is one of Stelle's most reliable archetypes, as many of its components can be acquired within the first couple of days, making it a great starting point.

Example Early Game Path

Core Synergies

  • Molten Ball Blaster works best when you can maximize its Charge triggers. Opt for the fastest Tools you can find.
  • Blow Torch and Box Cutter are the most efficient early game Tools.
  • Angle Grinder Drone pairs perfectly with Joystick to create even more effective Charges.
  • Goggles acts mostly as filler for now, but becomes a key component later on.

Tips & Tricks

  • Finding a natural upgrade from the Weapon/Medium vendor is actually quite common, so consider rerolling (if you can afford it) to get a big power spike.
  • If you know you can defeat a PvE encounter, swap out Box Cutter to help preserve some of its Damage (not a high priority, never risk a fight because of it).
  • Toolbox is incredible for this build, beyond its usual Economy boost. Upgrade to Silver ASAP, and take advantage of useful duplicates.

Common Filler Items

  • Clockwork Disc
  • Gyro Gunsight
  • Oxygen Mask
  • Steam Washer

Example Mid Game Additions

Core Synergies

  • Precision Calipers provides solid Haste support and unlocks incredible Crit scaling with Goggles.
  • Rivet Gun is a decent slot in, but truly shines once upgraded and assembled into the late game setup.

Tips & Tricks

  • Molten Ball Blaster has strong snowball potential, but it's important to hit your upgrades to keep momentum. If you're losing, search hard for Large items.
  • Multitool and Hydraulic Squeezer are solid mid game inclusions until replacements are found.
  • Always take advantage of Hammer and Wrench whenever possible. They are both reliable ways to hit many of the important upgrades.

End Game Build Breakdown

Core Synergies

  • Stelle's Workshop enables an incredibly fast loop with Angle Grinder Drone and Rivet Gun. As the sole Drone of the build, it'll spam Charge like crazy.
  • Precision Calipers + Goggles combo provides essential Crit for Molten Ball Blaster. This ensures its Damage is still strong enough for the late game.

Tips & Tricks

  • With the Stelle's Workshop + Angle Grinder Drone + Rivet Gun loop, you can reliably utilize Stelle's powerful Flying skills (which otherwise aren't great).
  • Hangar is a great alternative to Stelle's Workshop, but instead trades a bit of speed and efficiency for a situational Bonk effect.

Situational Variants

  • Radar Dome is an alternative setup that trades Charge speed for Multicast. This works best when Molten Ball Blaster has a Shielded enchantment.
  • You can then utilize more Burn (or Fiery) items alongside Smoke Detector to capitalize on Radar Dome's Multicast.
