The Colosseum (colloquially known as "Colosseum Raid") is a Second Sea location and the host of a special event that takes place in the Rose Kingdom every fifteen minutes after server creation. The event is a difficult onslaught of enemies consisting of 10 waves. On every fifth wave, the participants will be presented with a boss battle.
Every time the Colosseum Raid is completed it has a cooldown period of another 15 minutes until it can be started again. This period begins after the raid is completed, and is not synchronized with other servers; this means that servers who complete the raid quicker or slower than the average squad will have a slightly different refresh time.
Wave 5 will spawn one random boss from a pool rather than a number of enemies, which the participants must defeat to continue. This pool includes but is not limited to: Thunder God, Neptune, Borj, Crab King Cho, Bellom, Captain Zhen, Ryuma, Pharaoh Akshan and Gravito. Bosses spawned via the Colosseum still have a chance to drop their normal items.
The boss Lucy spawns on Wave 10. Lucy is not randomized and will always spawn; defeating him will conclude the event and distribute rewards to each player. Upon defeating Lucy, all players who participated in the raid are rewarded Rare or above fruits In addition to this, Killing Lucy is a requirement to unlock the Gomu-Gomu no Mi's Gear Second.
Tactics & Tips[]
- Enemies gain more health and damage the more players participate in a raid. If the player has the luxury of a Private Server, it may be recommended to limit the amount of participants.
