An up-to-date Rare Apparel Spreadsheet
Before I go any further I would like to thank the person who put this together one Somatezib on the data-mining discord.
Now, most of the spreadsheet is self explanatory however there is one particular aspect of it that I feel deserves further explanation.
(*7) List of activities with radiant rewards
What does this mean exactly?
Well it means that every time you run one of these activities the game rolls a dice to determine what regional reward you will get. There are eight regions in total, so each time you complete an event you have a 1 in 8 chance to get any given region. This is made slightly more complicated by Burning Springs and Skyline Valleys regional rewards being exact copies of the forests droptable. That means if you are farming these events whose rewards are not fixed you have a 3 in 8 chance to get a reward from the forest.
What this all means in practice is that you can complete one of these events, say Enclave: Dropped Connection, get a piece of rare apparel, like a forest camo jumpsuit, and then jump over to another version of Enclave: dropped connection and get an entirely different piece of rare apparel like a leather coat.
