[Review updated after Creator's response - Still 5 stars. Since my original review, Ben has added a portrait-oriented version.]
This is the best DM reference for use with a landscape-oriented [and now portait-oriented with the new edition!] DM's screen that I've found. I particularly like that it includes the Action Options from the DMG (Climb Onto Bigger Creature, etc.). It also has a section for basic stats for up to 8 characters (character and player name, AC, HP, Passive Perception, and Spell Save DC). That section is super handy for use with a wet-erase pen if you are using the Hammerdog DM Screen. [Also, Ben includes both PDF and Word versions of the screen, allowing you to easily make changes for your home rules.]
I use this product for the DM side of my screen, and the Player's Cheet Sheet by Sean Wickett (also on DMs Guild) for the Players' side. Sean Wickett's product has a nice, but brief, "Combat Progression" section, but I'd like to see a more detailed and complete list of the action options. [Ben recommended Player's Quick Combat Guide, by Adam Hancock, available on DMs Guild, which I've added to the Players' side. It is a flow chart that shows the sequence of combat.]
[Having used this screen for many months, now, I modified the section with the blanks for character stats to include a line for Level, Class, and Race. And I print a version of this section on labels to create name-badges for players. I DM for total noobs at least once a month, and every week I run a group that rotates different players, so name-tags and the sheet with the blanks for character stats is a big help.]
Great job, and thanks for creating this!
