When I’m trying for precursor,I usually buy batches of 300 weapons or so and I get like ~10 exotics If I’m lucky,maybe 1 or 2 named.
But when I’m mystic forgin’ the rares I get from world bosses (random rares,like 1 warhorn,2 spears,1 pistol etc) I get an exotic pretty often,and most of the time they are named.
I’ve done all the bosses today (temples,etc..) and used the MF with the rares,and I got:
Faithful (Axe)
Naga Fang (GS)
And Yakkington Leggings
So,with ~15 (?) rares I got 3 exotics,and all of them were named.
I’m almost sure this isn’t just me being “lucky”,I think the exotic drop rare is higher with different weapons than using the same weapon (i.e 4 GS),but of course you can’t just want to get your Dawn for your Sunrise trying with random weapons,but who knows…maybe it can also drop precursors with a very little higher chance?
