Tactics

Instance map

After entering the instance, the group appears in a selection room.

To move to the Core, the party leader must talk to NPC Yalo To Core .

After choosing the boss, the party will be transported to the bridge on the third floor of the Cruma Tower in a parallel dimension. At the end of the bridge, you will see a room with monsters. Among the monsters, there is a Yalo Key Keeper Lv. 78 running around in a circle. There are rumours that he can turn into a powerful demon. But this is not certain. Be prepared for the fact that the monsters are very strong!

Kill the monsters near the entrance to the room and wait for Yalo to reach you. Use crowd control skills to slow and kill him. After Yalo dies, the party leader will receive Cruma's Secret Key NG , which opens the Boss room.

There are two ways to get into the boss room. The first way is to clear the way, killing monsters one after one. The second way is to have the tank gather all the monsters on the way to the door. The group leader opens the room, and the tank leads the monsters into the corner between the columns to the right of the door. The group then kills the monsters with mass abilities.

After you've dealt with the monsters and restored your health and mana, you'll have to kill a mini-boss to remove the Core's invulnerability effect and lower its defence.

• If your group are mages — go to the right side of the room and kill Crippled Magic Giant Core Henchman Lv. 78
• If your group are warriors — go to the left side of the room and kill Crippled Physical Giant Core Henchman Lv. 78

Both monsters unleash an area-of-effect ability in the sector directly in front of them. To simplify the fight, we recommend pulling the monster from the platform beneath it rather than from the side of the stairs. The tank should gain the monster's attention and move it to a corner, positioning its back toward the group.

After the Minion dies, the Core loses its invulnerability and receives a permanent debuff that reduces physical or magical defence:

• Boss Physical Defence Decrease Lv. 1
• Boss Magical Defence Decrease Lv. 1

These effects share a common type with some debuffs of similar effect. For example, after killing a Physical Minion, you will not be able to apply the effect of Hex Lv. 1 to the Core

After removing the invulnerability, you can attack the boss. At this point, 10 monsters will spawn near the Core — similar to those you encountered in the previous room. Focus on eliminating them first before targeting the boss. The Core is vulnerable to all debuffs, but remember that the boss does not damage players. The primary threat comes from the waves of monsters, so managing them is key to victory.

Each time the Core's health decreases by 10%, a new wave of monsters will spawn. How you handle them will depend on your group's strength and coordination. If you’re confident in your abilities, continue attacking the Core while using area-of-effect skills to eliminate the monsters. However, if your group lacks coordination or gear, it’s safer to pause your attack on the Core and focus on defeating the monsters before resuming the fight.

Levelling SA

On the boss, SA is levelled from level 10 to 14. The chance is individual for each group member:

	10 → 11	11 → 12	12 → 13	13 → 14	14 → 15	15 → 16	16 → 17	17 → 18
Core Inzone Boss Lv. 80	15%	10%	5%	3%	0%	0%	0%	0%

Reward

In the fifth season of MasterWork, drops and experience for completing the instance became personal.

Experience

The experience for killing the Core is fixed for each group member, which means it doesn't matter how many of you there are — 7 or 9, each player will receive the same amount of experience.

Pets gain experience without penalty for the difference in levels between the owner and the pet.

Personal reward

After the Core dies, each player who was near the boss will receive a box with personal rewards

Core's Box NG . Contents of the box:
