Core
Core guards its chamber deep inside Cruma Tower. It never moves, but on Ashenvale it fights back: hitting it from far away is no longer free damage.

Where and how to get in
Section titled “Where and how to get in”Core sits in its chamber inside Cruma Tower, an open-world lair: no ticket and no instance. The chamber itself drains a share of your max HP while you stand in it, so bring healing.
Who is in the fight
Section titled “Who is in the fight”| NPC | Level | HP | Role |
|---|---|---|---|
| Core | 82 | 10,435,403 | boss |
| Susceptor | 82 | 21,155 | escort ×9 |
| Doom Wraith | 82 | 25,299 | escort ×3 |
| Death Knight | 82 | 21,831 | escort ×10 |
Susceptors, Death Knights and Doom Wraiths guard the chamber and come back a few minutes after they die.
How it fights
Section titled “How it fights”Core has three phases by HP: normal above 70%, overload from 70% to 30% and critical below 30%.
| Skill | When | Target | Effect |
|---|---|---|---|
| Electric Bolt | Always | The tank, in melee | 15% of max HP and a bleed |
| Electric Rain | Always | The most crowded group, ranged players first | 25% of max HP and 15% of max MP, in an area |
| Electric Flame | Below 70% HP, with 3 or more players within 400 | Everyone around Core | 1% of max HP per second for 10 s, and a slow |
| Electric Stun | Below 70% HP | The closest melee player who is not the tank | 3 s stun |
| Critical | Below 30% HP | — | Every skill comes faster; a message warns everyone nearby |
Tips: spread your ranged players, since Electric Rain looks for groups, and keep only the tank in melee once Core drops under 70%.
