You can now open adventures purchased from the FG store while inside the OSE ruleset (No extension required).  Simply open the encounter, drop the monster link on the Necrotic Gnome on a "NEW" NPC record and it will self populate.  (Saves are based on Monster HD)  OR you can drop the encounter link on the Gnome inside the encounter and it will convert the ENTIRE encounter at once.

update: 3/22/22 Filters out the second attack for "large" creatures from the 2E record.

Double check all data as some store module are missing important information like THACO or HD.

See the video below for how it works (note: Token now transfers)
