In the Colosseum players can send a team of five Heroes to battle against other players in the same Kingdom. The Colosseum unlocks at Castle level 10.
Players start out at the bottom of the Rankings, which is dependent on the number of players available in the Kingdom. Players move up in the Colosseum by challenging other players. Battles in the Colosseum are automatically played out from the moment the Deploy button is clicked, so leaving the Colosseum before the battle ends has no effect on the outcome. When players defeat another player of a higher ranking, they will exchange rankings with that player. The amount a player may rank up for each battle will decrease as the player moves up through the ranks.
There are two different Hero Formations in the Colosseum:
The Defense Formation will be used automatically when other players challenge the Heroes.
The Offense Formation is used when the player challenges other players, and can be changed before every battle.
The Might, Grade and Rank of the Heroes being used will contribute to the overall strength of the Formation.
There are five free entries daily in the Colosseum, and players can use Gems to get additional entries. The Adult Skill of the Familiar Bonehead will also provide 3-10 additional entries every 1-2 days, depending on the skill level. Players can change their opponent list at no cost.
Players can view the previous 20 battles by clicking the Battle Report button. The top 100 players can be viewed by pressing the Player Ranking button.
When a player leaves a Kingdom, their position in the ranking will be replaced by a NPC named Guard. The ID following the Guard name will vary depending on ranking; Guard.2000 being the weakest and easiest to defeat, and Guard.0001 being the strongest.
Colosseum battles are heavily influenced by Constellations, which are stat boosts applied to certain Heroes during Colosseum battles. Choose Heroes that fulfill the requirements to receive the Constellation boosts, which change weekly.
Constellations may help or hurt your Hero Formations, depending on which Heroes benefit from the current Constellation. Press the Constellations button to view the current Constellation, as well as the upcoming one.
