Radonas & Gigantitamul (Level 69 Progression Bosses)
Radonas (Rain Esa) and Gigantitamul (Mill TWD) are the first major progression bosses players will encounter in Chimera Online.
Although both bosses are level 69, they become relevant as soon as players approach level 60.
Why They Are Important
Upon reaching level 60, experience gain is blocked until the appropriate boss has been defeated.
- Radonas can be found in Rain Esa.
- Gigantitamul can be found in Mill TWD.
Defeating either boss unlocks further character progression and allows leveling beyond 60.
Recommended Preparation
Suggested Level: 60+
Suggested Group Size: 4 Players
Recommended Equipment:
- Complete Red Valley Fame Set
- Fame equipment enhanced to Level 55
- Basic understanding of stun and seal mechanics
Boss Characteristics
Both bosses possess approximately 15 million HP and are designed around group mechanics rather than raw damage output.
Powerful Area Attack
The most dangerous ability is a devastating area-of-effect attack.
- Cast time: approximately 5 seconds
- Deals massive damage to everyone nearby
- Can often wipe unprepared groups
Using Stun and Seal abilities to interrupt or delay this attack greatly increases the chance of success.
The Damage Escalation Mechanic
Like many enemies in Chimera Online, these bosses become stronger the longer they attack the same target.
Every successful hit increases the damage they deal to their current target.
At first this increase is barely noticeable, but because the bosses survive for a long time, the effect eventually becomes overwhelming.
Even level 80 characters can be overwhelmed if they attempt to tank the boss alone for too long.
Tank Swapping
The key to defeating these bosses is periodically changing who is being attacked.
When the boss switches targets:
- The accumulated damage bonus resets.
- Incoming damage returns to manageable levels.
- The fight becomes significantly safer.
Groups should coordinate tank swaps whenever damage starts becoming difficult to sustain.
Low-Gear Strategy: Hit & Run
For players with weaker equipment, a popular strategy is:
- Engage the boss.
- Deal as much damage as possible.
- Retreat when resources run low.
- Return and continue the fight.
Because Radonas and Gigantitamul have very slow health regeneration, progress is rarely lost.
This method takes longer but allows undergeared groups—or even extremely determined solo players—to eventually secure a kill.
Rewards
Defeating these bosses provides access to powerful Fame Equipment, which forms the foundation of character progression beyond level 60 and prepares players for the next stages of endgame content.
Key Takeaway
Radonas and Gigantitamul are less about raw damage and more about understanding mechanics. Interrupt their powerful AoE, rotate tanks regularly, and even modestly geared groups can overcome one of the most important progression gates in Chimera Online.
