Lightning/Death Sentry Assassin (Trapsin) Build for Diablo 2 Resurrected
The Trapsin Assassin is a crowd controlling expert who utilises a variety of ranged abilities to keep herself safe while her traps attack enemies. Overall, the Trapsin is a competitive build with good survivability, damage, and utility. Trapsins are in fact one of the easiest characters to play in the game and are highly recommended for newer players.
Possibly one of the most underrated characters for newer players, the Trapsin Assassin truly has it all. High damage, multiple damage types, high survivability, good speed, and great crowd control. Highly recommended for anyone looking to get into Diablo 2 PvM.
You can check the viability of this build in PvM by consulting our PvM Tier List.

MrLlamaSC's Trapsin Video Guide
We also have a video guide that goes over the build, if you prefer that instead of or in addition to our written guide.
In Diablo 2, stats that affect action speed (known as frames) for attacking, casting, blocking, and recovering from a hit can almost never be taken literally. For example, gaining 10% Increased Attack Speed from an item will not necessarily translate into 10% faster attacks. To achieve faster actions, certain breakpoints must be reached, which vary for every class. The tables below list how much of a given stat is required to actually improve the action speed of the class for the stated action.
Faster Hit Recovery Breakpoints
|Hit Recovery Breakpoints|
|Frames to perform action||9||8||7||6||5||4||3|
|Faster Hit Recovery required to reach frame||0%||7%||15%||27%||48%||86%||200%|
Faster Cast Rate Breakpoints
|Faster Cast Rate Breakpoints|
|Frames to perform action||16||15||14||13||12||11||10||9|
|Faster Cast Rate required to reach frame||0%||8%||16%||27%||42%||65%||102%||174%|
Faster Block Rate Breakpoints
|Faster Block Rate Breakpoints|
|Frames to perform action||5||4||3||2|
|Faster Block Rate required to reach frame||0%||13%||32%||86%|
Attack Speed with Flail
Attack speed is used for laying Traps, not cast rate. This only includes Increased Attack Speed from gear. Burst of Speed will positively affect your Trap laying speed as well, although slightly differently than what is shown in the table, as it uses more complex calculations.
|Attack Speed with Flails|
|Frames to perform action||14||13||12||11||10||9|
|Increased Attack Speed required to reach frame||0%||6%||16%||30%||52%||89%|
You can either hire a Defensive ( Holy Freeze) or Offensive ( Might) Desert Guard Mercenary in Act 2, Nightmare difficulty, depending on whether you want to slow monsters for added safety or improve the overall damage of your Mercenary.
- Weapon: Ethereal Infinity
- Body Armor: Ethereal Fortitude
- Helm: Andariel's Visage socketed with a Ral Rune
