Mid-Boss, also known as the Mid Boss and The Boss, is a powerful neutral jungle boss with strong attacks and a regenerating shield to defend itself. Teams of Heroes may attempt to kill Mid-Boss to harvest potent Rejuvenator buffs, improving the strength of three Heroes that claim them.

Overview

After 10 minutes have elapsed in a match, the Mid-Boss will spawn underground in the sewers in the center of the map. Its arrival is announced through a loud roar, followed by the Patron's announcement, "The Mid-Boss has arrived". While Mid-Boss is alive, a golden Rejuvenator symbol will appear at its location in the minimap, and above the entrances to the Mid-Boss pit.

The path to the Mid-Boss' pit can be found in entrances marked with the Rejuvenator sign, at the Blue lane. These entrances will also have a glowing Rejuvenator symbol above them when the Mid-Boss has respawned.

The Mid-Boss is initially dormant and will not attack anyone outside its pit. As soon as a player has entered the pit, the Mid-Boss will attack by channeling a bright purple beam onto them. If multiple players are inside the pit, it will prioritize the closest one. Additionally, the Mid-Boss can only be damaged by players who are inside its pit, and will be completely invulnerable to outside attacks.

Unlike most units, Mid-Boss has a special shield surrounding it at all times that prevents it from taking health damage. In order to actually harm it, enough damage needs to be dealt to deplete the constantly regenerating shield, which can prove difficult for individual or unprepared players. The damage shield starts at 35 HP and increases at 5 HP/minute (85 HP when the Mid-Boss first spawns).

Once Mid-Boss has reached 70% Health, it will roar once again, announcing to both teams that it is close to death.

Health Scaling

Mid-Boss' Health scales linearly from when it spawns. For every minute that passes after it has spawned, it gains an additional 195 Health, which is added to its 13000 Base Health.

Death

When the Mid-Boss is slain, a Rejuvenator crystal will spawn above the pit and begin its slow descent, which takes 6 seconds. The Rejuvenator crystal is not targetable as it descends and cannot be claimed until it has fully landed on the ground. Once landed, attacking it with a heavy melee attack grants a Rejuvenator Credit to the entire team. Each heavy melee hit on the crystal grants one credit (up to 3 for the first Mid-Boss kill, and 4 for subsequent kills).

Rejuvenator Credit

Main article: Rejuvenator

The Rejuvenator credit grants all team members a buff that allows them to revive in the place of their death after 3s. When a player dies, they respawn in place, lose the buff, and their team’s Rejuvenator credits are reduced by 1 (each player can consume only one credit). The buff also increases Health, Fire Rate, and Spirit Damage at the following rates:

Source	Buff Strength
Hero Fire Rate	+15%
Hero Maximum Health	+10%
Hero Spirit Damage	+15%

The Rejuvenator credit lasts 4 minutes. The top UI bar displays the remaining Rejuvenator credits. Once all credits are used, the buff is removed from all team members.

Respawn

The Mid-Boss respawns 7 minutes after its first death. Then it respawns 6 minutes after its second death, and 5 minutes after its third and subsequent deaths.
