Trap

There are 15 different kinds of traps currently ingame as of Patch: NW.1.20130416a.19

They are categorized into 8 different types; Arrows, Arrow Bank, Floor Vent, Darts, Dart Bank, Spike, Blade, and Spear.

Traps are triggered by both human players and monsters, so it is a common tactic especially by Trickster Rogues (who can see traps before they go off) to lure enemies into them.

Arrows:

Arrow Trap (Normal Arrows), Arrow Trap (Poison Arrow)

Fires a single normal arrow at the player. One arrow slot, one trigger plate. Poison Arrow Trap applies a poison on the player, acting as a Damage over Time (DoT) for a short period.

Arrow Banks:

Arrow Bank (Normal Arrows), Arrow Bank (Poison Arrow)

Fires multiple arrows, each aimed at a different point (Default is set in a line parallel to the traps facing position). Three arrow slots, one trigger plate. Maximum range is 60 feet. Poison Arrow Bank applies a poison on the player, acting as a Damage over Time (DoT) for a short period.

Floor Vents:

Vent Trap (Acid Fog), Vent Trap (Disease), Vent Trap (Poison Fog) and Vent Trap (Steam Cloud)

All vent traps cause damage to players who step on it. The effect size is a radius of 6'x6'(feet), a little larger than the area of the trap itself.

Acid fog slows you for a short period.
Poison cloud adds a poison DoT on your character for a short period.
Both Disease and Steam have no additional effects.

Darts:

Dart Trap (Normal), Dart Trap (Poison)

A single dart slot combined with one trigger plate. Effective range is 60 feet. Poison Dart Trap applies a poison on the player, acting as a Damage over Time (DoT) for a short period.

Dart Banks:

Dart Trap Bank (Normal), Dart Trap Bank (Poison)

Fires multiple darts, each aimed at a different point (Default is set in a line parallel to the traps facing position). Three dart slots, one trigger plate. Maximum range is 60 feet. Poison Dart Bank applies a poison on the player, acting as a Damage over Time (DoT) for a short period.
