Superboost was a process in Skylanders: Ring of Heroes used to power up Skylanders. When boosted, a Skylander's basic stats are increased, including their MAX skill level. Superboost is automatically activated when players summon duplicate Skylander five times regardless of the rarity. They can only be obtained either from Dark Subjugation or if the player uses the Premium Summon at least 25 times.
