Guild/Asgard/Guild Raid/Osh the Eternal Keeper

Osh the Eternal Keeper is the boss of the Cradle of the Stars Guild Raid.

Stardome
The Stardome is orbited by the Defense Spheres it generates. The Spheres are activated on approach, attacking nearby heroes. At the same time, they can be attacked to deal significant damage to the Stardome.

Wormhole
Osh creates a Wormhole that begins attracting all around it and dematerializes the remaining Defense Spheres on the battlefield. Each Sphere that enters the Wormhole damages all heroes.

Planet Parade
All Defense Spheres remaining on the battlefield line up for a Planet Parade for the duration of 5 seconds. If all Spheres are destroyed before the Parade ends, Osh awakens and boosts the remaining heroes for 5 seconds.

Nightmare Visions
The Defense Spheres that are not destroyed during a Planet Parade force the heroes to succumb to sleep, unleashing Nightmare Visions that attack other heroes. To awaken the heroes, their Nightmares must be defeated. Once the Nightmares perish, Osh awakens and boosts the remaining heroes by 5 seconds.

Meteor Shower
A Meteor Shower blazes through the battlefield, damaging all heroes for the duration of 5 seconds.
