Kemet
What changed for the alliance in Kemet: Seth version 1.5?
Posters relaying the v1.5 rules say the alliance can no longer buy purple tiles, Seth starts with purple action tokens equal to the number of allies plus one, and the three rectangles at the top right of the Osiris board are no longer used (Tomb tiles go where they are built). This is how forum posters describe the update, not a designer ruling.
