Summoner Build | Torchlight 2 Best Engineer
Valdo stepped into the cave. The darkness was immediately broken by the crimson eyes of Chitin Warriors. They screeched and charged.
"Go," Valdo whispered.
He didn't fire a shot. He simply cast Spider Mines.
Five small, metallic arachnids deployed from his pack, their legs scrambling over the wet stone. They darted underneath the charging warriors and detonated in a chain of explosions that shook the cave walls.
The Chitin warriors stumbled, their carapaces cracked. That was Bertha’s cue. The Sledgebot surged forward, her massive piston-fists slamming into the ground, sending a shockwave that knocked the creatures into the air.
Tick-Tock opened fire from the rear, a steady stream of tracer rounds shredding through the disoriented mobs.
Valdo stood in the center, a conductor of an orchestra of violence. He fired his pistols casually, triggering his Supercharge ability. A bolt of energy lanced out,
The Engineer summoner combines the Engineer’s mechanical mastery and turret-centric toolkit with strong minion support to create a defensive, high-damage playstyle that excels at solo and group PvE. This essay explains design goals, core skill and stat priorities, gear and crafting guidance, playstyle and micro-decisions, endgame scaling, common variations, and tips for mod and multiplayer compatibility.
6. Forcefield (1 point) This skill scales with your shield’s armor. At 1 point, it gives you an absorb shield equal to a percentage of your shield’s armor. At max rank, it scales worse. Keep it at 1 point and spam it. It makes you virtually immortal while your bots work.
7. Blast Cannon (1 point) You will use a shotgun/wand + shield. Blast Cannon converts your weapon damage to fire damage and pierces enemies. At 1 point, it’s a cheap way to apply status effects (burn) and knock back enemies who get too close. Do not level it; the mana cost becomes prohibitive.
8. Ember Reach (1 point) A mobility tool. It pulls you to an enemy or a friendly bot. Use it to escape stunlocks or jump to your Sledgebot when surrounded. One point is all you need.
If you want to break the traditional hack-and-slash mold, the Engineer Summoner is the most relaxing, thematic, and surprisingly powerful build in the game. It turns Torchlight 2 into a tower defense game where you are the tower.

Immobilization Copter (15/15): Passive support that slows enemies and reduces their damage. 🛡️ Defensive Essentials

The rain in the Steppes hammered against Valdo’s goggles, slicking the metal surface of his chassis. He stood at the mouth of the Brood Cave, the entrance exhaling a foul, chitinous stench.
Beside him stood "Big Bertha," a hulking Sledgebot frame, its piston-arms dripping with hydraulic fluid. To his left skittered "Tick-Tock," a Gun Bot with a polished brass barrel. To his right, the faint, crackling blue hologram of a Heal Bot hovered, emitting a soothing, rhythmic hum.
"Ready, boys?" Valdo asked, his voice tinny inside his helmet.
They didn't answer with words, but with the whir of gears and the click of reloading mechanisms. This was the Summoner Engineer—the puppet master of metal, the undisputed king of the horde.
Valdo wasn't like the other Engineers. He didn't care about swinging a massive great wrench or firing a heavy cannon. He let his creations do the heavy lifting. He checked his skill logs one last time before descending into the dark.
You are a walking command center. Your personal damage is secondary — your spider mines, gunbot, and sledgebot do the heavy lifting. You stay alive through shields and heals while your swarm overwhelms enemies. This build works brilliantly in Veteran and Elite, especially in co-op.
You are a pet-focused Engineer. Your Sledgebot, Gunbot, and Spider Mines do most of the damage. You support them with Healbot, Forcefield, and crowd control. You rarely swing your weapon — instead you regen mana and spam summons.
1. Sledgebot (Max - 15 points) This is your tank. Your champion. Your best friend. The Sledgebot is a massive mech that taunts enemies, has a huge health pool, and deals respectable physical damage. At max rank, it has an AoE ground slam that stuns. Always keep this bot active. If it dies, run away and resummon it immediately.
2. Gun Bot (Max - 15 points) Your primary damage dealer. This turret fires explosive charges that deal fire damage in a large radius. It scales with your Focus and Character Level, not your weapon. Two Gun Bots can overlap their AoE to melt entire screens of trash mobs. Always have two active (you unlock a second at tier 2).
3. Spider Mines (Max - 15 points) Do not underestimate these little guys. They are cheap, you can have up to five active, and they seek out enemies. Upon reaching an enemy or expiring, they explode for significant fire damage. They are your cleanup crew and boss killers. Spam them constantly between fights.
4. Healing Bot (Max - 15 points) The reason you never die. This bot pulses a heal-over-time that affects you, your pets, your other bots, and even allied players. At max rank, it also restores mana and reduces physical damage taken by 15%. Keep this up 100% of the time. No exceptions.
5. Immobilization Copter (Max - 15 points) The ultimate debuff. This hovering drone slows enemies by over 50%, reduces their armor, and—most importantly—has a chance to stun them every second. Stunned enemies can’t attack. Combine this with your Sledgebot’s taunt, and melee enemies become helpless pinatas.
