I’ve moved to torment 16 doing bounties the fact that it is one percent chance should be clarified from primal to ancient to legendary or set
Set is same as legendary, just the bonus depends on the number of set pieces.
There is no official information about the chance of primals. The chance of primal circulating is the statistics done by some players.
The ratio of ancient vs normal legendary is known to be 1:10.
The ratio of primal vs normal legendary is 1:400 (estimated).
Mathematically this sounds astronomical in terms the amount of percentages in your favor it is far less than what most people take a chance on from my thinking its like running as many 100 g.r. rifts just to find 1 primal ancient at a time
The only Primal bet you can make is on the 94.99% chance that there will be a deal breaking stat on that Primal drop.
depends what stat ur looking for besides legendary other than that set bonuses stay about the same unlike legendary bonus
