Best Engineer Summoner Build - Torchlight 2

The Torchlight 2 Engineer Summoner is not the flashiest build, nor the fastest, but it is one of the most reliable and intellectually satisfying. You are not a hero charging into battle; you are a general commanding a steel legion. When your Sledgebot taunts a champion pack, your two Gun Bots turn them to ash, and your Healing Bot keeps everyone alive, you’ll realize the power of letting machines do the dirty work.

So, grab a shield, spec into Focus and Vitality, and start building your automated empire. The armies of the Netherlord fear the sound of gears turning.

Go forth, Bot Lord. Your factory awaits.

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. The Torchlight 2 Engineer Summoner is not the

"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.

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.

Valdo knew the secret to a summoner wasn't just quantity; it was synergy. He had allocated his skill points with surgical precision over the last thirty levels.

The Workhorses: His first investment had been into Sledgebot. He had sacrificed the chaotic shock of the Blast Cannon for the reliability of a melee tank. He had pushed the skill to rank 15. At that level, Bertha wasn't just a machine; she was a juggernaut capable of staggering enemies with every swing, drawing aggro away from Valdo’s fragile, pistol-wielding frame. Your gear choices differ from a melee Engineer

Next was Gun Bot. At rank 15, Tick-Tock was a DPS monster, spitting lead with increased range and damage. The Gun Bot was the reason Valdo could stand back and simply watch the carnage.

The Support: But the true hero of the build was the Heal Bot. Valdo had maxed this out early. It didn't just patch up his armor; it provided a massive boost to his physical armor rating and healed his entire mechanical entourage. A dead robot does zero DPS. A healed robot is an eternal war machine.

The Game Changer: Finally, there was the ultimate skill: Bulwark of the Aegis. He had poured points into the Defense tree to unlock it. It was the lynchpin of the strategy. Every time Valdo was struck, Bulwark of the Aegis had a chance to trigger a massive, party-wide heal. It meant that to kill Valdo, the enemy had to kill the healer by hitting him, but hitting him healed him. It was a maddening paradox for the monsters.

The Summoner Engineer is one of the most relaxing yet powerful ways to play the game. Instead of swinging a hammer, you act as a commander, deploying an army of robots, gun turrets, and zombies to overwhelm enemies.

Your gear choices differ from a melee Engineer. You are looking for specific affixes.

What to Look For:

Weapon: Wands are usually the best choice because they often roll with minion stats and cast speed. However, you can use a Shield + Wands or a Pistol + Shield for the extra defensive stats (Block chance). You do not need high weapon DPS; you only need the stats on the weapon.

Weapon: Wand + Shield (wand for Focus scaling, shield for block).
Alternate: Staff (2H, Focus + elemental damage, but less defense).

| Skill | Points | Why | |-------|--------|-----| | Emberquake | 5–10 | Scales with Focus. Good when surrounded. |

❌ Avoid: Fire Bash, Flame Hammer, Onslaught, Aegis of Fate (not needed), Coup de Grâce (you don’t auto-attack).
