All players who contributed enough damage towards the boss during the Battle Phase are awarded a certain amount of Raid Balls, with top contributors receiving additional balls. Raid Balls offer a chance to catch the boss. Legendary bosses have a 50% catch chance per ball, with non-legends having a 25% chance.
Raid Balls
The amount of Raid Balls awarded to each player depends on the size of the raid party, and the percent of damage dealt to the boss.
