Publisher: Dungeon Masters GuildPrintable, Index card-sized monster stat cards.
Personally, I have found that the monster columns on the adventure league modules can be hard to follow, especially in combats with multiple types of creatures represented and the BBEG of the adventure.
After seeing Matt Colville use index cards he said he made and printed in one of his videos, I decided to do this for myself for adventure league and am now sharing it here.
The 4x6 cards are basic monsters and mini bosses, the 5x8 cards are the BBEGs of the adventures with their additional abilities or monsters who have enough abilites that fitting them on a 4x6 care was not feasable.
