A new update of the Pathfinder files is available from the automatic updates mechanism within Hero Lab.
This update adds Melee Tactics Toolbox to our existing Player Companion #18 package. This package is available for $4.99 and already contains Giant Hunter's Handbook and Familiar Folio.
In the Campaign Setting line, we've added Tombs of Golarion to the existing Campaign Setting #13 package. This package already contains Undead Unleashed, Ships of the Inner Sea, Lost Treasures, and Belkzen, Hold of the Orc Lords, and is available for $4.99.
This update also incorporates a recent FAQ that codifies the damage increase/decrease mechanics and implements several things like mounted charging with a lance and vital strike that required damage dice multiplication, as well as including many bug fixes.
