Imp Overlord

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

Environments

 * Rallypoint Delta
 * Scorched Acres
 * Abyssal Depths

Decimate
The Imp Overlord violently and repeatedly lashes out in front, dealing an immense 5 x 200% damage to targets at close range. It will only perform this move when there is a target in melee range.

The skill has a cooldown of 1 second and a proc coefficient of 1.0 per hit.

Spike Volley
The Overlord swipes and flings 5 to 6 spikes at its target in a horizontal fan pattern. Each individual spike deals 30% damage and inflicts for 3 ticks. Spikes that don't strike a target stick in the ground where they fall, dealing the same amount of damage to players that touch them.

The skill has a cooldown of 3 seconds, and the Imp Overlord can store up to 3 charges. Each spike has a proc coefficient of 0.8.

Abyssal Teleport
The Imp Overlord periodically disappears, re-materializing in a different location after a few seconds. Before it reappears, a large red circle appears on the ground, as well as some floating particles, to telegraph where it will appear next. Players within the ring take considerable damage when the Imp Overlord teleports back.

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 Overlord is unwillingly dragged back to its original dimension.

Tips

 * Given the Imp Overlord's high movement speed and ability to teleport, maintaining a safe distance can prove difficult. Even so, staying on the move is preferable to standing still; 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 one's steps too often. The area will eventually become littered with planted spikes and the likelihood of accidentally walking backwards into them increases the longer the battle goes on. To that end, items that enhance vertical mobility, such as or, make dealing with Overlords' spikes considerably easier.
 * While fighting an Imp Overlord with melee attacks can be perilous due to its Decimate attack, the player can attempt to hug the uppermost part of its body to avoid being hit by the ground slams.

Trivia

 * In the first game, the Imp Overlord was a community-made boss suggested on the Risk of Rain forums by Seria-Myouna and illustrated by Daimera.
