Materials you leave on the ground become turret range and attack speed. Our tier list puts Builder in C tier: Structure range and attack speed from unspent materials. Slow and positional.

The stat line

• You start with 1 Builder's Turret
• Every 5 uncollected materials are converted into 1% Structure attack speed and 1 Structure Range at the end of a wave
• Engineering modifications are increased by 50%
• +20 Harvesting
• You can't have structures
• -30% pickup range
• Damage modifications are reduced by 75%

Builder comes with the Abyssal Terrors DLC. Unlock: Unlocked by default. Winning a run unlocks Lighthouse.

How the run plays

Every 5 uncollected materials at wave end turn into structure stats, so the Builder plays against instinct: let materials pile up near your turrets and collect only what you need to shop. The starting Builder's Turret gains extra projectiles at range thresholds. Engineering is the damage stat; Harvesting replaces the pickups you skip.

Weapons

Builder fits the Tool or Support classes best. Start with Taser and hold six weapons of one class for the set bonus; the weapons list shows everything in the Tool class with per-tier damage.

What to buy, what to skip

Engineering and Harvesting, Structure-tag items, Max HP. Avoid Pickup Range.

The shop favours Engineering items for Builder, so expect to see these often: Pencil, Book, Landmines, Turret, Duct Tape, Cog, Compass, Incendiary Turret.

The mistake that ends runs

Vacuuming every material like a normal character and ending the wave with nothing converted.

Co-op partners

• Streamer — Builder turns ground materials into stronger turrets. Streamer stands still inside the turret ring, gaining armor per structure and materials per second.
• Old — A smaller arena keeps turrets in range of everything.
• Pacifist — An economy partner keeps materials dropping while the builder leaves them on the ground.
