Why haven't you nerfed Seismic Trap? 3.20

We have nerfed Seismic Trap several times this year. We understand that competitive players would like Seismic Trap to be nerfed yet again so they don't feel obligated to play with it for ladder pushing. Outside of this context, it doesn't appear to be used by an extremely large number of people (it's top twenty, but not meta-defining). We will investigate whether we can change it for situations that are relevant to racing but we can't promise anything yet.

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).
  • 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.

Item acquisition

Seismic Trap can drop anywhere. Drop level: 28.
