Imp Overlord

The Imp Overlord is a returning Boss Monster in Risk of Rain 2. Being a Boss, the Imp Overlord may be encountered after initiating a stage's Teleporter Event. It can otherwise spawn naturally during higher difficulties.

Decimate
Strictly a melee attack, the Imp Overlord will violently lash out in close proximity to itself, dealing an immense 5*200% damage to those caught in the radius. It will only perform this move when there is a target in melee range.

The skill has a cooldown of 1s and a Proc Coefficient of 1.0 per hit.

Spike Volley
The Overlord swipes and flings 5 to 6 spikes in the direction of its target in a horizontal cone pattern. Each individual spike deal a decent 30% damage and causes bleeding for 3 ticks. Spikes that don't make contact with a target plant themselves in the ground. Same amount of damage will be inflicted to those who make contact with planted spikes.

The skill has a cooldown of 3s and can stack 3 times. Each spike has a Proc Coefficient of 0.8.

Teleport
Imp Overlords will periodically disappear and re-materialize in a different location. Before it teleports back, a large red circle will be present on the ground, as well as some floating particles, to telegraph where it will re-appear next. Those standing within the ring as the Imp Overlord teleports back will be dealt considerable damage.

The skill has a cooldown of 9 seconds. This attack is not to be confused with the Overlord's death animation, in which a portal emerges and the boss is unwillingly pulled back to its original dimension.

Tips

 * Given the boss' high movement speed and ability to teleport, keeping your distance from an Imp Overlord can prove difficult. Regardless, it's best to always be on the move. While the Overlord's Spike Volley can be a nuisance, the alternative - its melee attack - is much more dangerous.
 * While kiting an Imp Overlord, it's best to avoid retracing your steps too often. The area will eventually become littered with planted spikes and you're liable to accidentally walk backwards into them as you fire at the Overlord. To that end, those with items that enhance vertical mobility, such as Hopoo Feathers or Milky Chrysalis, have an easier time dealing with the boss' Spike Volley, given its horizontal nature and the player's ability to stay off the ground and avoid planted spikes.
