I'd like to have a simple reference sheet for this, as people will frequently reference sourcebooks with a simple acronym. Perhaps this question can be made into such a sheet.
Most have been easy to find, some that come to mind are:
- DMG*: Dungeon Master's Guide (I, II, II, etc)
- PHB*: Player's Handbook (I, II, III, etc)
- HotFL: Heroes of the Fallen Lands
- HotEC: Heroes of the Elemental Chaos
- HotFW: Heroes of the Feywild
- Heroes of the Adjective Noun: Books like the above, essentially extensions of the PHBs
But I started this question because Google has failed me, what is AV2 for?
- AV2: ???
Any others worth mentioning?
