  "body": "## Preparation\n\nCombining requires at least two free copies. Attempts count pairs: 10 copies permit at most 5 attempts. Eligibility depends on type, class and sometimes the item design.\n\nOrdinary combining uses essence; Ultra creation uses separate Ultra Essence and separate rules. Check materials, cost and the displayed chance before proceeding.\n\n## Historical base chances\n\n| From | To | Chance |\n| --- | --- | --- |\n| Normal | Rare | 95% |\n| Rare | Unique | 90% |\n| Unique | Elite | 85% |\n| Elite | Super Unique | 80% |\n| Super Unique | Super Elite | 50% |\n| Super Elite | Legendary | 40% |\n| Legendary | Epic | 30% |\n| Epic | Mystic | 10% |\n| Mystic | Secret Class | 1% |\n\nStructures, blessings, skills, equipment, laboratories, spheres and cards may contribute bonuses. Check applicability and stacking against the current displayed chance; a historical sum of maximum bonuses does not guarantee a result. Ultra has a separate table.\n\n## Splitting\n\nThis concerns eligible combined items in classes 2–10 where the previous class can be combined. It is not arbitrary stack division. Complete output quantities and loss rules are not established.",
