Lostland

1. Lostland opens for 2 weekly sessions. Each session lasts 2 days. 2. Lostland is available in three difficulties: Normal, Expert, and Hell. You must clear a stage at the current difficulty to unlock the next difficulty. 3. For each Lostland session, you can select up to 10 Heroes to enter. You can deploy up to 6 Heroes in a battle. The HP and Killed status of your Heroes and enemies will not reset at any time during a Lostland session. If a Hero you selected for a current Lostland session is consumed elsewhere within your account, you can no longer use that Hero, nor can you select another Hero to take the consumed Hero's slot. 4. You must clear all obstacles in your path. You can only move through 1 tile at a time. Not every obstacle contains enemies; pay attention to what the obstacles look like! 5. There are a total of 3 stages in Lostland. Defeat the final Lostland Guard of each stage to unlock the next stage. Win Soulstones of powerful Heroes and other rare rewards after clearing each stage.
Blessed Wings - Revive all dead Heroes and restore all Heroes
