Extended information
Safras, the hand of Ragnaros, the fire demon, is the very commemorative first orange equipment in "World of Warcraft". The legendary hammer Savras, the Hand of Ragnaros the Firelord, is a powerful weapon held by Ragnaros the Firelord. It has the highest DPS and damage limit at the time, and is owned by warriors, paladins and shamans. It is seen as a great honor.
The orange weapon of the same period as Thunderfury and Windseeker's Blessed Sword, the Balrog Hammer, seems to have been overwhelmed by the legend of Thunderfury and Windseeker's Blessed Sword. The orange weapon was a product of MC. However, the cost of the orange hammer was sky-high. For players at the time, especially its best owner, the shaman, it was simply too difficult to own him. In comparison, it was still Thunder's Wrath and Windseeker's Blessed Sword are easy to get.
