Launches a mine to the target location, where it arms itself after 2s. If an enemy approaches the mine it detonates, causing poison damage to all enemies within 1.5m and afflicting them with vulnerability for 10s. The poison cloud then persists and continues to damage enemies each second. (Note that you can only have at most 3 mines at once. Placing a fourth mine destroys the mine you created first.)
