Champ's Challenge is a minigame found in Olympus Coliseum in Kingdom Hearts 358/2 Days. The minigame coincides with Mission 46, where Roxas is tasked with collecting hearts.
In this training, Roxas is told by Phil to collect as many points as he can by defeating Loudmouths or smashing barrels within 1 minute 30 seconds. He can gain additional hearts by defeating Loudmouthss during the training.
Strategy[]
Smack the barrels toward a group of Heartless to destroy them before the chain rings around them disappear. Collecting 230 heart points during the training session is enough to complete the mission; however, Phil offers you to train until you've collected 460 or more heart points. Doing this fills the Mission Gauge 100% and Phil will leave. You are able to attempt this three times, otherwise the mission ends.
