Grandparent

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

Environments

 * Sky Meadow

Rock Throw
The Grandparent throws a large rock at a player, causing heavy damage and high knockback on impact. The rock is destroyed if it collides with any solid obstacle.

Gravity Orb
The Grandparent spawns a slow-moving orb that moves toward a player for a moderate duration. Any player caught in its gravity well will be pulled toward the orb. This orb (and its gravity well) can pass through all obstacles. Players should avoid being caught by these orbs in certain levels as they can result in being dropped into bottomless pits.

Solar Flare
At 50% health and below, the Grandparent prepares a star-like orb above its head, which creates an enormous sphere of heat. Any entity caught in its large area of effect that does not take cover (except for and Grandparents) will be continuously  and receive the stacking  debuff, increasing the amount of damage they take from burning.

Trivia

 * Prior to the Anniversary Update, an early version of the Grandparent was left unused within the game code with a vastly different appearance and skill set.
 * The Grandparent more closely resembled a large, misshapen, two-headed that was partially submerged in the ground. It would create teleportation fields to catch the player and bring them within striking distance, as well as spawn eggs from which Parents would eventually emerge.
 * The Grandparent's spawn animation will launch players within it at a high velocity, in most cases off the map, so be careful when it is spawning.
 * The spawn animation itself deals no damage, but can indirectly hurt you via fall damage or launching you into another attack.
