How does it determine if you get a Master Writ? Is it random? Mira hasn’t gotten one since the 7 voucher one either last week or the week before.
Well, according to Gina Bruno your chances increase by how much research you have done and how many COMPLETED styles you have learned. There is some variable factors like how many daily Writs you do with how many characters; and the extent of their learned knowledge vs how many sets are out in the world.
That means that there is a "Sweet Spot" you can hit where these criteria all meet perfectly to give you the maximum level of Master Writs and vouchers = this was running completely opposite of what they said right up until that patch two months ago.
According to Zen; every time they add new styles to learn to the game world; it supposedly increases the Master Writ drop rate for everyone = Again, I've noticed a complete opposite effect in this as well.
I think whatever Zen THINKS the criteria is; some Dev miscalculated something somewhere and it is totally skewed from what they say.
A couple months ago (a few weeks before Clockwork City dropped) they said in the Patch Notes that the Patch was supposed to "Fix the drop rate on Master Writs." = And it worked!!! For about 2-3 weeks suddenly I was getting Master Writs galore with huge Voucher numbers on them! Then they added Clockwork City and the numbers dropped to nothing again.
Right now that drop in Master Writs and Voucher numbers since Clockwork City came out still remains; but I'm still getting more Master Writs now than I ever did before that Patch a couple months ago (Thank Goodness!).
So yeah, Zen Devs have probably miscalculated something again. In other words, "Everything is working as intended..."
