Based on gameplay experience at level 55 and above, this guide explains how to avoid common mistakes when opening free reward chests, how to survive the mid-game difficulty increase, and why knowing where to buy Raven 2 Crystal can help you bridge gear gaps when RNG from those chests falls short. 

The Free Items Received via In-Game Mail

Around level 50 to 55, several reward chests arrive in the in-game mail. These include a random Stella ranging from Rare to Heroic tier, a Rare or Heroic selection chest, and an accessory chest containing one of each accessory type.

The purple Heroic Stella is not guaranteed. The probability of obtaining high-tier items from random boxes is extremely low, estimated at approximately 0.01 percent for top tiers. Players should not expect Heroic items from random rewards.

Accuracy Is Not the Priority at Higher Levels

Many guides recommend prioritizing Accuracy above all other stats. For level 55 and above, this advice requires revision.

A level 55 character fighting level 60 to 61 monsters with 217 Accuracy (including holy water and food buffs) experienced minimal missed attacks. Accuracy was not the limiting factor.

The primary challenge at level 50 to 55 is survivability, not accuracy. Quests become significantly more difficult. Monsters deal substantially more damage. Players are frequently surrounded by multiple enemies and defeated before mana reserves are depleted. The Abyss dungeon becomes nearly impossible to complete. In documented gameplay, a character fighting only one to three enemies simultaneously still watched health points decrease while using potions. Encounters with seven enemies at once result in certain defeat.

Recommended Chest Selection

The optimal choice from the accessory chest is the belt, followed by the amulet for players requiring MP recovery.

The belt provides +8 defense, +6 damage reduction, bonus HP, and additional attack stats. This combination offers defensive benefits while maintaining offensive capability.

The amulet serves as a suitable alternative for players experiencing MP recovery difficulties. It provides defensive and support-oriented stats.

Earrings and rings should be avoided from this chest. Although earrings offer strong offensive stats including final damage, attack speed, and accuracy, they do not improve survivability. Damage cannot be dealt while defeated.

Relic Upgrade Strategy Without Loss

When selecting a relic from the chest, the following upgrade strategy prevents loss of the only copy.

Take the first relic and upgrade it to +1. Take a second relic and upgrade it to +2. Use the +2 relic as material to upgrade the first relic from +1 to +3. If this upgrade fails, take another relic and upgrade it to +3 instead. Once a +3 relic has been obtained, take a +2 relic and attempt to upgrade it to +4.

This strategy preserves progress at each step. The only leveled relic is never risked. Even after multiple upgrade failures, a usable item remains.

Survivability Requirements for Level 50 and Above

Before investing in damage stats, the following elements should be secured.

Melee defense is the highest priority, as most monsters deal melee damage. Damage reduction stats should be stacked wherever available. Damage decrease against normal monsters provides additional protection. A belt with defensive stats must be equipped. A sufficient supply of HP potions should be maintained and used during combat. An emergency teleport scroll should be placed on the quick-access hotbar.

Emergency Escape Configuration

The inventory favorites system enables quick escape. Navigate to the inventory and open the favorites section. Add the Home Teleport Scroll to favorites. Assign it to a quick-access slot. When defeat is imminent, open favorites, select the teleport scroll, and exit the area instantly. This configuration is particularly important on mobile devices where menu navigation requires additional time.

Mid-Game Difficulty Progression

From level 1 to 49, the game operates at normal difficulty. Damage and Accuracy can be prioritized without significant issues.

From level 50 to 54, difficulty increases substantially. A balance of offensive and defensive stats becomes necessary for survival.

At level 55 and above, difficulty becomes severe. Defense, damage reduction, and HP must be prioritized above most other stats.

In the Abyss dungeon, difficulty reaches extreme levels. A full defensive configuration is required for survival.

Final Recommendation

The Rare or Heroic chest should not be used for offensive accessories such as earrings or rings. The belt should be selected instead, or the amulet for players needing MP recovery. Defensive stats should be stacked through the item collection system, filtered by melee defense and damage reduction against normal monsters. Defensive relics should be prioritized. The smart upgrade strategy should be used to avoid gear loss.

The core principle is that damage cannot be dealt while defeated.
