Raid 101

In this guide, we'll explore the four key raid types available in Lost Sword: Daily Raid, Party Dungeon, Avalon, and Star Reincarnation. Mastering each one unlocks valuable, unique rewards that are vital for enhancing your team's capabilities.

Each day rotates elemental bosses, requiring strategic team adjustments. You receive 3 free entries daily (or use Boss Raid tickets for additional attempts). After setting a personal high score, Players unlock the ability to Sweep instantly to claim daily mission rewards. For competitive scores, manual skill activation with precise timing is essential.

Party Dungeon

You receive one free entry daily, plus extra attempts using Party Raid Tickets from events or exchange shops.

Rewards include Dragon/Abyss gear and upgrade materials, Mystic Stones for specialties, Fairy Queen Tokens for shop exchanges, and Refinement Stones.

Star Reincarnation

Star Reincarnation is a bi-weekly rotating endgame mode demanding significant roster depth: two full teams (5 characters + 3 pets each) for a total of 10 characters and 6 pets. Each rotation features unique boss mechanics and buffs, constantly shifting the optimal team meta. Rewards scale with performance.

Stage Rewards: Diamonds + Goddess Stones (used to boost Divine Power via constellations), tiered at 10M/100M/300M damage.

Ranking Rewards: Diamonds, Regular Refining Stones, and Equipment Option Change Tickets based on final leaderboard placement.

Avalon

Avalon stands as the game's premier guild event, where guilds compete to achieve the highest score within their chosen castles. Each member receives 6 attempts to contribute. Castles feature three distinct phases: the first two (walls and gates) don't deal damage, making healers unnecessary and allowing for optimized offensive lineups. The final phase pits players against a unique Castle Guardian boss, which varies depending on the castle attacked.

Attempts yield valuable rewards: the first two attempts on any castle grant 100 Diamonds each, while the third attempt on a castle increases this to 150 Diamonds. Crucially, guild rewards are based solely on their highest-scoring castle. Therefore, strategically focusing efforts on just one or two castles is highly recommended for maximum efficiency.

At the event's conclusion, members receive substantial rewards—including Guild Coins, Fairy Tokens, Diamonds, Equipment Chests and Equipment Substats Reroll Ticket. —determined by their guild's final ranking.
