Seismic Trap is a spell skill that throws a trap when activated, releases multiple shockwaves that deal physical damage for its duration.

Skill functions and interactions

Once the trap is triggered, it will spawn a seismic device in its triggered location. This device releases several waves every 0.9 seconds.

You can improve the DPS (damage per second) in different ways:

  • Releases waves every 0.9 seconds: Increasing trap throwing speed reduces the delay between waves, improving DPS.
  • Base duration is 3.5 seconds: Increasing duration increases the total number of waves per seismic trap (improving the total potential DPS per trap).
  • Releases 5 waves: A number of waves will be released at each interval. Increasing this number increases the potential DPS per trap.
  • Increasing area of effect increases the radius of each wave, making it possible to overlap more waves.

Because the seismic device spawns waves around it, you can maximize overlap (and therefore, DPS) by throwing the traps around the mob instead of throwing them at the mob's feet.

However, this changes with enough AoE. [1]
