Prison

Prison
Building Type	Advanced

The Prison allows a player to capture enemy Leaders with Level 10+ Castles. Execution wait times depends on the Leader Level; upgrade the building to reduce wait time. The Strix familiar's Quick Fix skill can reduce the wait time by up to an additional 6 hours. Once the wait time is over, the prisoner must be executed within 6 hours, or it will escape.

Steel Cuffs are needed to build and upgrade the Prison. There are 25 levels to upgrade, and the total of 20,000 are required to fully upgrade a Prison. Lv. 25 grants Capture boost. The Prison is a permanent building, meaning that once it has been built in a player's Turf, it cannot be demolished.

Tips

It is better to buy Steel Cuffs × 1000 for 10,000 Gems as opposed to buying a single Steel Cuff for 15 Gems. The same applies to Altar (Soul Crystals) and Battle Hall (War Tomes)

Other ways to earn small amounts of Steel Cuffs include Guild Bonus Chests when a guildmate buys Special Bundles, Guild Fest rewards, certain Vergeway: Verge Guardians stages and certain Kingdom Chapters.
