Traps in Diablo 2 is one of the three skill trees available for the Assassin, the other two being Martial Arts and Shadow Disciplines.
Important Note: With the release of Patch 2.4 these skills has suffered some changes:
General Modifications:
- With Trap skills, there are multiple underused skills that can be more effective or have improved synergy distribution
- For Lightning and Fire Traps synergy from Death Sentry was removed to give more build possibilities.
- Fire traps are receiving damage synergy improvements to make them more effective at higher difficulties
- The Blade skills are receiving multiple improvements to make them more viable to dedicate builds around these skills.
List of changed Skills:
Information
Sometimes, the incredible martial prowess and awesome psychic capacity of the Assassins are not enough to battle all forms of magic-wielding menaces. To supplement her array of tools and abilities, the Assassin has access to an ingenious group of devices. These mechanisms, engineered by Viz-Jaq'taari sages, have been perfected over many years of use. They range from simple thrown missiles and bombs to more complex proximity-triggered sentries.
Important Notes
- There is a limit of 5 Traps.
- Traps are very effective in Normal and later on into Nightmare. Players traveling to Hell might find traps start to become less effective at higher acts due to Monster resistances and Life. Traps are, however, easy to use and there is not much risk of harm which balances this out.Traps can be used at higher difficulty levels for additional help and the Death Sentry's Corpse Explosion ability can be great anywhere.
- Certain items will allow a player to lower an enemy's resistances and/or heighten elemental damage. These items will not function with most traps as some traps are minions of the character and the damage is not generated directly from the character in question.
- Blade Sentinel, Blade Fury, Blade Shield: All three blade skills receive an additional 50% penalty to the "weapon" portion of the damage while wearing 2 handed weapons. So equipping a thunder maul would make blade fury add only 3/8 of your 'normal attack' damage instead of 3/4, and would make blade sentinel do 3/16 instead of 3/8, and blade shield do 1/8 instead of 1/4.
- Traps function as golems and summons, that means that they are not affected by items that give +lightning/fire damage or -% lightning/fire.
