The World Monster (also called "The Cerberus") is a new kind of monster. A banner linking to it appears on everyone's Home page twice a day at specific times, every day, 15 minutes before you can start hitting it. It remains alive for 30 minutes, and you can collect up to 1 hour after its death.
The Word Monster is not a permanent feature. It is made available more or less arbitrarily for indefinite periods of time.
Refine Crystals were introduced with the World Monster. You get them as a reward when you collect, but they also drop randomly when hitting it.
Using bigger stamina buttons gives more chance at a drop. Reports seem to indicate that using the 200 stamina button gives a Crystal almost every time.
The World Monster can't be failed. Whether he gets killed or not, at the end of the 30 minutes, it will be displayed as a victory with 0.00% Life Remaining. Everyone will be able to collect.
What matters to get the rewards isn't directly the amount of damage you dealt, but your rank among all attackers. Only the first attacker on the leaderboard will get Odin, all the others will get varying amounts of Refine Crystals.
1. Event Time : 8:00 & 20:00 PST.
2. Collect rewards end: 9:30 & 21:30 PST.
3. Every player attacked the monster will gain rare items.
4. Please collect your rewards before they expire.
5. Damage doesn't count towards "Monster Leaderboard"
6. Equip your best loadouts and wreak havoc!

- The World Monster is the main way to acquire Refine Crystals. As stated on the Refine page in-game: "You can get Refine Crystals by fighting World Monster at 8:00 & 20:00 PST". The Refine feature was introduced January 9, 2018, about 10 weeks after the World Monster.
- Its HP is displayed in percentage at the bottom right of the monster.
- The only tabs available are "Attack log" and "Chat log", as there is no need for a "Status log", and the loot is displayed when clicking on the "question mark" button.
- Getting in the top 1000 requires very little stamina (sometimes 1 stamina is enough). So you can get 2 Refine Crystals twice a day very easily as long as you show up for the battle and collect.
- Anyone can comment on the chat tab, and many use it to promote their army code.
- When the World Monster was first introduced, the best reward was already Odin, but the other rewards were Common Chaos Shards.
- Its HP has been adjusted. When it was first introduced, high level players were racing for the first place to get the best reward, so it would die within 2 minutes with several players dealing billions of damage, even though it had a huge amount of HP (30 billion? More?). After a while, its HP would never reach 0.00% so it was lowered (it has about 15 billion HP currently). However nowadays (September 2018) most of the time it doesn't even come close to dying before the battle time is over (it often has over 75% HP remaining).
