At Salma Hotel in Hellfire Peninsula, there is an NPC on the right selling the formula of small emeralds in their early 300 s (no prestige). Use this to flush until it stops, and make a few rings.

I can buy a blue jewelry formula, which is cheaper now anyway. It's estimated to be below 100G (it used to be 300+), so I can buy some corresponding sapphires to make it up. It's easy now.

The difficulty of BOSS is not very difficult in the past TBC3. 13. Level 85, phase 4.3, even hunters can brush by themselves. Perhaps there is no shortage of members in the description of the above skills, which undoubtedly destroys the powerful skills of the group.

Objectively speaking, although he is called "Shook"-because he came out earlier than Kel 'Thuzad, he is more difficult to deal with. This can be seen from the land reclamation of guilds all over the world.

No guild can kill this guy until the difficulty of C 'Thun is reduced. Later NAXX, 4DK was almost the finale difficulty. By TBC, Illidan had not reached the difficulty of Knox and C 'Thun.
