World bosses
Every 6 hours (03:00, 09:00, 15:00, 21:00 server time), level 300+, up to 40 players.
The event
Portals open next to the temples; the boss appears 2 min later and leaves after 45 min if it is still alive. The bosses take turns.
Level 300 or more; at most 40 players in the lobby and the arena. No player-vs-player damage inside.
Your score is your damage on the boss plus the healing you did on others and the damage you survived (tanking counts half).
Rewards
Everyone with a score of at least 0.25% of the boss's health: 500,000 gold to the bank and a share of 10,000,000 by score; 3 Orb of Upheaval, 1 Orb of Fate, plus a share of 60 Orb of Upheaval, 25 Orb of Fate.
A boss gear item: 15% + share x 30%; a boss-only unique: 0.5% + share x 3%.
The top 3 in Damage (title Bossbreaker), Healing (title Lifewarden) and Tanking (title Bulwark) get extra orbs, a better unique chance and a title for 7 days.
