From publisher blurb:
Creature statistic cards for all the Aberration, Celestial, Elemental, Fey, and Fiend 'System Reference' creatures of the 5th edition of the world's most popular Fantasy RPG.
The cards are a deck of 58 cards (56 creature cards, one cover/checklist card and one license card).
The document is a PDF of cards set up to be printed at 2.75"x3.75" and trimmed to 2.5"x3.5". Also included is a second PDF with all the cards on 8.5"x11" pages, 4 cards per page.
The text on the cards is generally a 9pt font, but some cards have 7pt to 8pt font if the text wouldn't otherwise fit on the card even after shortening the text. (All meaning/game information was preserved.)
