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

 

Build mechanics in short

Trap Support has no cooldown now in 3.3 and you can throw 15 Traps instead of 3 (in the end-game you can have around 23 traps at a time on the ground). THIS IS A BUFF, so now it's all about your Throwing Speed + cooldown for lengthy 8 second Traps.

Arc is a lightning, chaining spell with highest amount of chains in the game. Chain means it will "zap" between enemies. In 3.3 Arc does 15% MORE damage per remaining chain. If 1 enemy is on screen it will be 105% more damage, which is DOUBLE the damage. So it's now good against single target.

We will use Arc+Trap in a shaper 5L gloves for clearing maps and 8 second fat Lightning Spire Trap in a 6L for bosses.

Run around, throw traps, don't run INTO packs or you will die. For the same reason i don't have a dagger and a shield here. Even with Acrobatics, this is still a pretty low HP build. Going ES route is pretty much same, maybe a little better.
Don't stand near bosses or you will die.
