"The artist need not to be present to make a lasting impression."

The Saboteur focuses on improving his traps and mines with utility bonuses and additional traps and mines.

Arc is a lightning, chaining spell with highest amount of chains in the game. Chain means it will "zap" between enemies. That's why we can get high damage on single target in this build. What's more, this build very cheap and endgame viable!

Pros & Cons

Pros

• + great map clear speed
• + serious firepower with very low investment
• + end-game viable (need very good reflexes for end-game though!)
• + massive life regen (up to 20% per second and even more with Tinkerskin)

Cons

• - Squishy as low Life pool (hard to go over 5k)
• - Pretty slow with a wand and Flame Dash
• - sketchy for HC

Helmets

Lion Pelt

Armours

Tinkerskin

Gloves

Hydrascale Gauntlets

Zealot Gloves

Gloves with +1 Trap can boost your damage by around 25%. But they will most likely drop your resists into abyss :D. If you can still balance your resists, use them for sure! It's a HUGE BOOST! 

Belts

Stygian Vise

Boots

Arcanist Slippers

Rings

Any good Elder ring is a good pair with Shaper Ring

Amulet

For the amulets and rings: high life, crit multi, spell damage, resists. Of cause Opal rings would be sick. 

Shaper 5L (Trap Support): Arc-Trap & Mine Damage-Cluster Traps-Elemental Focus/Lightning Penetration (Pen will work better against bosses)

6L Spire: Lightning Spire-Added Lightning-Trap & Mine Damage-Controlled Destruction-Elemental Focus-Concentrated Effect (once again Lightning Pen can be used against tough bosses like Shaper)
