FAQ
What Is a Summon Unit in Super Fantasy Kingdom, and How Does It Differ From a Worker?
A summon unit is a dedicated fighting unit used to defend your kingdom during the night cycle. They are distinct from workers, who are responsible for resource gathering, construction, and refining during the day.
Workers do not participate in combat and cannot be sacrificed for achievements, though they are essential for growing your economy. Summon units are the core of your fighting force, gaining XP and leveling up when fed after battle.
Are the Unlock Conditions for Summon Units Permanent Across All Game Cycles?
Yes, once a summon unit is unlocked, it becomes permanently available for recruitment in all subsequent runs. This permanent progression mechanism is tied to the game’s Glory system. This makes sure that even failed runs contribute to your long-term kingdom-building efforts.
If an Unlock Condition Requires Reaching a Certain Day Must This Be Done in a Single Successful Run?
Yes, conditions that require surviving a specific number of days, like surviving 14 days without a quarry to unlock the Troll, must be accomplished in a single game cycle. The progress is tied to the current run’s longevity and specific constraints.
Does Sacrificing a Unit (to Unlock the Lich) Mean Sacrificing a Worker or a Fighting Unit?
Sacrificing a unit to unlock the Lich involves sacrificing a dedicated fighting unit, not a worker. Workers cannot be sacrificed. This is performed at the Elemental Tower, a late-game structure that requires five Gold Ingots to build. Sacrificing a fighting unit transfers its XP to the Elemental, a unique unit that cannot gain experience through normal feeding methods.
Do Summon Units Contribute to the ‘Field X Airborne/Summoner/Mage Units’ Unlock Requirements?
Yes, the units you successfully recruit and deploy contribute to requirements that necessitate fielding a certain number of unit types. For example, deploying five mage-type units will help unlock the Shroom unit, provided all other conditions are met in Super Fantasy Kingdom.
