How to Beat C'Thun

Client cosmetic “Gnomish Mind Control Cap” (feat:cthun, file Interface/Icons/INV_Helmet_49.blp). This is not a portrait of C'Thun.

C'Thun is the final boss of Gates of Ahn'Qiraj, zone 11 of 12, “The Old God Stirs”. On the community clock checked for 0.110.0, C'Thun arrives at 20:00. The run has already shown four earlier bosses. You unlock the next zone only by killing this one, on this class. Surviving until the timestamp is not the unlock.

Arrival

Defeat Nefarian in Blackrock Mountain on this class. The earlier clock, for context, is on the Gates of Ahn'Qiraj page.

Mechanics that are actually published

Every boss on this route, including C'Thun, enrages below 30% health. That is the shared rule. We are not attaching a private ability list. Hit points stay omitted: the 0.112.5 pass did not produce one boss health value to cite, and the older 0.103.1 figures were not re-measured.

Spend the enrage window on movement and on whatever your capstone already does to targets under 30% health. Execute-style talents, Warrior’s Mortal Strike route, and Hunter’s Aimed Shot resets are examples. A new card grabbed at 31% health will not come online in time.

Second to last. The talent tree should already be deep from Blackrock failures. Legendary gear starts its drop table in this zone and the next. A 20% base chance is not a promise.

Builds that fit this zone

• Warlock build. Dots on the boss, demons between you and the enrage. If the pet plan and the dot plan are both half-finished, you have neither.
• Hunter build. Pets do not replace a boss pattern. Keep distance when the final boss drops under 30% health.
• Druid build. A bear can stand in more of the enrage than a caster. A caster still has to move. Do not switch plans at minute 14.

If C'Thun is killing you, another clear of the previous zone is usually more talent experience than a new class. Then come back with the same capstone finished.
