I died once and become a Courier for the Dead in no time. Easy peasy. I died a second time and stayed dead for a good stretch; but no Courier. Was I just unlucky, or is the Courier a one-off event?[li]
It isn’t a one-off event, but it is dictated by the whims of the RNG and what cards it gives you while you are on the river.
A quick aside- besides reporting to the Widow, you can also use it to influence Chi Lan, the feared Black Ribbon Duelist.
Thanks Mordaine! Chi Lan is the very the reason I went back.
