You can kill Sha of Anger multiple times, but the loot is locked to once per week per character. The weekly reset, which usually happens on Tuesday at 7am PST, resets the loot eligibility for Sha of Anger and other world bosses. So if you kill and loot Sha of Anger on one day, you cannot loot it again with the same character until after the weekly reset. However, you can farm it on different characters each week for multiple loot chances. As for the respawn timer of Sha of Anger itself (how soon it appears again after being killed), it is random and typically varies between 10 and 20 minutes rather than a fixed spawn time like other bosses. The boss usually respawns around the Burlap Trail spawn point after this cooldown. In summary:
- Loot can be obtained once per week per character, reset weekly on Tuesday.
- Sha of Anger can be killed many times as it respawns every 10 to 20 minutes after being defeated.
