Acid Trap

Acid Trap is an Environmental Effect found in the Imperial Isle Guild Hall as well as the Raisu Palace mission.

Acid Trap does 20 armor-ignoring earth damage every second that the player stands in it, and the damage can be reduced with Mantra of Earth. However, using Winter and Greater Conflagration when combined with Mantra of Frost or Mantra of Flame does not change the amount of damage taken. Damage is not reduced by Runes, Shields or certain Warrior Armor, either.

Energy is gained when using Storm Chaser, since Acid Trap deals elemental damage, which makes it a good skill to use to grab the flag during GvG matches.
