Dungeons matter in Sailor Piece because players use them to compare entry rules, wave structure, rewards, difficulty, and dungeon purpose. This catalog lists 4 dungeons and keeps the important fields in one place: level, Difficulty, Boss, Time, description, and Rewards.
Use it to check names, images, requirements, prices, rewards, availability, and other listed details without opening each item one by one. When a value is blank, that detail was not listed clearly in the current data.

Rune Dungeon
The primary dungeon in Sailor Piece, accessed via Dungeon Island after completing the Dungeon Master quest chain. Features 15 waves of enemies with a 5-minute timer per wave — players can die unlimited times and respawn before the timer ends. The Rune Dungeon is the only way to obtain Runes — powerful end-game modifiers that provide large damage, defense, luck, and special effect bonuses. Runes have levels that increase by completing more dungeon runs. Selectable difficulty: Easy, Medium, Hard, Extreme — harder difficulties yield higher rune drop rates and more XP/money.
Boss Rush
A 15-wave, 300-second sequential boss fighting mode accessed via Rush Keys (dropped by all enemies in-game). 1 Rush Key is required per entry. To receive rewards, players must deal at least 10% of each boss's total HP. Earn Rush Coins to purchase upgrades from the Boss Rush Shop, including the Sun Armor (+115% Defense, +87% Damage, +25% Damage Reduction when fully upgraded, costs 250 Rush Coins). Maximum full upgrade cost: 6,625 Rush Coins. Selectable difficulty: Easy, Medium, Hard, Extreme. Escanor appears as a special boss with scaling drop rates (Easy 0.6% / Medium 0.85% / Hard 1.25% / Extreme 1.85%). The Boss Rush portal is located on Sailor Island.

Start with the grouped sections, then compare the fields that matter for this collection: level, Difficulty, Boss, Time, description, and Rewards. Images help identify entries when the game uses icons or thumbnails, while the list view is better for scanning many rows quickly. Missing values are left empty instead of guessed.
