Mini Mushrum

The  is a returning mushroom monster added in the Artifacts Update.

Skills & Behavior
A Mini Mushrum generally wanders around aimlessly. Upon death, its body can be seen going back into the ground while its cap still remains above ground.

Primary: Fiery Spore Bomb
The Mini Mushrum prepares a spore bomb, visible above its head, for 2.6 seconds (scales with attack speed), and then lobs it towards the target. The bomb can be thrown within a 5-60m distance and it takes 1.5 seconds to land. Upon contact it explodes dealing 300% damage with a proc coefficient of 0.5 in a radius of 5m with linear falloff. It also leaves a blazing circular area behind that deals 40% damage with a proc coefficient of 0.4 per tick. It ticks 5 times per second for 7 seconds. Getting hit by this also applies effect on the target.

The attack lasts for 4.4 seconds, which scales with attack speed. However, for sufficiently high enough values of attack speed charing, firing, and ending the attack can occur on the same frame.

This skill has a cooldown of 10 seconds.

Utility: Regenerative Ingrain
The Mini Mushrum plants itself firmly into the ground over 1 second (scales with attack speed), creating a healing circle around itself that has the same healing effect as. It heals for 2.5% health every 0.5 seconds in a radius of 7m, including any other monsters that happen to enter the area. The healing duration lasts for a maximum of 15 seconds, but the Mushrum can end it earlier by issuing a moving command after 7 seconds. Both of these values scale with attack speed, which means the higher the attack speed, the less effective health can be regained.

When the Mushrum unburrows, it does so over 0.8 seconds, which scales with attack speed.

This skill has a cooldown of 3 seconds but this is irrelevant as the minimum skill duration is longer than this.

Behaviors

 * 1) Use primary: the Mushrum must be within 60m from its target, have line of sight, and have at least 50% health.
 * 2) Flee: the Mushrum must be within 60m from its target and have less than 50% health. This behavior will be active for 3 seconds and cannot be selected twice in a row.
 * 3) Use utility: the Mushrum must have less than 50% health. This behavior will be active for 4 seconds. As a result, when the player gets the Mushrum to less than 50% health, it will run away 3 seconds and then heal. If the Mushrum is still below 50% health after it has finished with this move, it will attempt to flee and heal again.
 * 4) Chase: the Mushrum must be at least 30m away from its target.
 * 5) Strafe: the Mushrum must be within 30m from its target.

Tips

 * Players should always keep moving and scan their surroundings constantly when dealing with Mini Mushrums, since they can throw their Spore Bombs from a considerable distance. This can prove fatal if caught off-guard, especially from Elites.
 * The slowness inflicted by the fire field stacks with inflicted by Glacial Elites, making these Mushrums especially dangerous. Setting foot in the fiery area from these Elites, even if for a moment, will drastically reduce the player's movement speed and make escaping the continuous damage much more difficult.
 * Leaving a Mini Mushrum in a partially damaged state can be dangerous. Letting one heal can waste precious time, not to mention it can potentially heal other monsters as well.

Trivia

 * The Mini Mushrum was simply named "Mushrum" in Risk of Rain 1, which suggests that a larger monster related to it was a planned addition.
