Trapsins are great for MF-ing, as with high faster casting rate they can get to Bosses quickly, and they can wear magic find gear with minimal compromises. As with other Assassin builds, their survivability is not their greatest strength, so I’m not suggesting the build for hardcore.

Boss kills will also be fairly fast, but Uber Tristram can cause you trouble. Traps deal immense damage, so in endgame gear you will clear mobs in no time. You can start your ladder season with a Trapper, just don’t expect extraordinary performance, unless you are in a party that has Conviction aura or a necromancer with the Lower Resists curse. The playstyle is relaxing, once you put down the traps they will do their job and take care of enemy monsters. The build is quite expensive, for optimal performance you will need an Enigma in order to be able to move fast. It relies mainly on the attacking skill Lightning Sentry, but Death Sentry or Fire Blast can also be utilized to kill Lightning Immune monsters. The Trapsin (Trapper Assassin) is one of the strongest and most popular caster builds in Diablo 2 currently.
