Overview
There are 2 types of raid: World Boss and Raid Boss where a large number of players gather to target one boss monster. World Boss appears once a week for 24 hours. You can summon a Raid Boss by using Summoning Ticket'''. '''Each raid boss has different summoning ticket, and you can invite up to 10 friends to participate in the Raid Boss.

World Boss
World Boss appears once a week for 24 Hours and from defeating it, you can acquire gold and Medal of Victory, an item used to purchase a variety of goods in the shop. World Boss requires a raid ticket to attend, and you can hold up to 5 raid tickets that recharge 1 every hour. World Boss raid will automatically end after a set period, regardless of whether or not the boss is defeated.

Ranking
Ranking in World Boss is determined by the following 3 criteria:
 * Maximum Damage: Maximum damage dealt to World Boss by a single Attack

If there is a tie, the tied players will be ranked according to: '' Players can only use Lv.60 characters in the World Boss Raid and cannot use 2 same characters regardless of the number of their ★. Each character requires a 10 hour cool-down before re-use. ''
 * Cumulative Damage: Cumulative damage dealt to World Boss
 * Attack Score: The total number of character ★ that participated in World Boss 
 * The number of participation
 * Higher cumulative damage dealt to World Boss
 * Higher Maximum damage dealt to World Boss

''Ex. You cannot set 7★ King Lion and 6★ King Lion in the same party. Ex. Once Gawain is used in World Boss, regardless of its ★ you cannot use Gawain again until its cool-down is over.''
