Duel Colosseum The Duel Colosseum is a gameplay mode in " Dissidia Final Fantasy " . It is unlocked by completing Shade Impulse . Duel Colosseum pits players against an endless string of opponents chosen at random , rewarding them with medals in between fights which players can spend on rare items and trade accessories . Numerous rare trade accessories and equipment pieces can only be acquired by participating on the various courses , making Colosseum play practically a requirement if the player wishes to acquire better items . It is succeeded by the Labyrinth mode in " Dissidia 012 Final Fantasy " . Courses . Once the player choose their character , they must select one of the Colosseum courses . The Airship and Falcon courses are available from the beginning , while the Invincible and Lunar Whale courses must be bought from the PP Catalog . The Blackjack course is only available for purchase after completing Inward Chaos . After the course is chosen , the Colosseum screen will load . The player can suspend their progress at any time by choosing " Exit " on this screen . When the player quits , they receive PP proportionate to the number of medals they had at the time they quit , and are given a tally of all items they purchased in the Colosseum . The player is also given their score for that run . Colosseum Screen . On the Colosseum screen , the player is shown the following data : Cards . Cards are chosen from the hand and have various effects . Cards are divided into Enemy Cards , Treasure Cards , and Job Cards . When the player chooses to fight an Enemy Card , they battle that enemy in the shown arena . If the player is victorious , they win an amount of medals , the other cards in the hand are discarded , and new cards cycle into the hand . The player may choose to spend medals on Treasure Cards in - between fights , or to select any Job Cards in the hand . When the player loses a battle , assuming they do not have a Knight Card in play , they lose a number of medals and the hand area decreases by one . If the player thus loses too many times , the hand area vanishes entirely and the player must quit the Colosseum . Enemy Cards . Selecting an Enemy Card will pit the player against the shown enemy . The amount of medals won or lost increases according to the strength of the Enemy Card . There are three subsets of Enemy Card : Boss Cards are gold in color and always have high strength and reward many medals . However , Boss Cards are not discarded from the hand when another card is played and will remain in the hand until fought . Secret Cards are enemy cards with the highest possible strength , and do not award a predetermined number of medals - defeating them will double the player ' s medals , while losing to them halves the player ' s medals . Finally , Chaos Cards are red and pit the player against Chaos at the highest level of the selected course , with the exception of the Lunar Whale Course at 100 and the Blackjack Course at 130 . Like Boss cards , Chaos Cards are not discarded from the hand . Chaos Cards are worth 50 medals by default . Treasure Cards . Treasure cards offer players unique items or equipment at the cost of some of their medals . The items offered on each course vary depending on the course selected , with the exception of a handful of items that appear on all courses . In addition to acquiring rare trade accessories first - hand , the player can win Elixir - type trade accessories which can then be traded for other accessories in the Shop . Each course also has a custom equipment set that can be won . Job Cards . Job Cards give special effects that affect what cards appear in the hand . Some are one - time uses , others remain in effect until discarded . Job Cards automatically cycle out of play when the player already has three in play - the Job Card on the left will be removed to make way for the next card . A subset of Job Cards are the Status Cards , which negatively effect the player as long as they remain in play . Like normal Job Cards they can also be cycled out of play to negate their effects . Some Job Cards have their effects stack , while others do not .
