The Drop Chance of Tier Sets in the Great Vault (Raid, Mythic+ and PvP) - Data from Community Submissions

Want to know what the drop chance of Tier Sets are in the Great Vault? We've collected some data from the community to estimate what the drop chance of Tier is.

Quick Summary

From a Google Form, I collected data from the community on what players have received from the Great Vault. From 321 Great Vault submissions and over 1,500 weekly objectives complete, we've seen the rough data:

Raid Row (Killed Tier Boss): ~13% Raid Row (Haven't Killed Tier Bosses) ~3.5% Mythic+ Row: ~9% PvP Row: ~3.5%

*The PvP result likely has the largest source of error due to having the fewest submissions by far. You can see the breakdowns on each of the Raid, Mythic+ and PvP rows in the Great Vaults below.

Here are the raw results from the data.

Raid Row

Here is the data from the Raid Row. Specific to the raid row, Blizzard announced that bosses that drop tier will increase your changes of receiving that tier slot. Therefore, there are two categories when getting tier: Killed Tier Boss and Didn't Kill Tier Boss, where players noted whether or not they defeated the matching tier boss.

Across the total of 694 reported raid objectives, assuming each box has the same chance to drop tier, here is the data combined across all 3 box slots.
