This page is about both playing an DMing (DM and GM are the same in AD&D) Advanced Dungeons & Dragons 1st and 2nd Edition on Roll20.

Macros and Attributes

AD&D 2nd Ed Roll Templates

The AD&D2e Character Sheet Template has several built-in Roll Templates.

Tips

Multiple roll templates can be combined in one macro if desired:

Maps

This section only really applies to a DM

Before you do anything else with a map, make sure you have the page settings right. Nothing is more annoying then making your map look all nice and neat and then realizing you made some critical mistake and have to start over. AD&D uses squares, so make sure you are in squares. Make it big to start with, making it smaller is easier than making it bigger. One unit is 5 ft (unless you really need to change it for some reason, 5 ft is best) and a 1 unit grid is best, with both grid color and background color depending on the map and the preference of both players and DM(some prefer no grid at all when playing but the grid really helps when hand drawing a map). Fog of War and Dynamic Lighting can wait until after you draw the map, but should be dealt with before your players see the map, as determined by play style and personal preference.

Now that that you have the major set up complete, a choice has to be made: hand draw in Roll20, import a drawing you make elsewhere, or use a drawing from online. If you pull a map from online or your library, you may need to align it and move it into position. Once you finish with your map, you now know how big it is. If you followed the earlier recommendation and made your space too big, after moving everything into place you now shrink it down to fit your actual map you are using (or just leave it too big to help confuse the players).

Characters and tokens

While each group is different on what they do for characters and tokens, A few things are standard. You will want a character page for each character. The DM will likely have a long list of NPC characters and might or might not share those with the players. If the DM shares the NPC pages, they can use the "GM notes" section to record info the players shouldn't know. Finally, you will likely benefit from setting a default token for each PC and NPC and attaching the bars (aka: the "bubbles") to a specific attribute. Remember that if you do not set a current and a max value, the bar will not to show up, but when you click on the token the "bubble" for its current value will still show.
