Hi Samuel, Errata is a word for printing errors. Some things were not printed correctly despite all the attempts at making sure everything was going to be done correctly. These can include small things like spelling errors or layouts that didn't quite get done properly, or it can be much larger issues, like those listed here, for Frosthaven: ---------- MAJOR ERRATA Please read: For first printing copies, there are two major errata that could significantly affect gameplay, which players should be aware of: There is a deck of cards in envelope 81 whose order should be reversed. If you pull it out and the visible card is titled "T___ of W___", reverse the order of the deck so that card is the first drawn when the deck is face-down. Envelopes 24, 37, 44, 85, and 90 have the wrong rule sticker numbers printed inside the flap of the envelope. Envelope 24 should list sticker 10 Envelope 37 should list stickers 11 and 13 Envelope 44 should list stickers 12 and 14 Envelope 85 should list sticker 15 Envelope 90 should list stickers 1, 5, 8, and 9 ---------- These are the errata that are being corrected. There are, to my knowledge, no changes to the box contents other than correcting these printing errors. No new components, no changes to the classes, just correcting the printing errors from the 1st printing.
