Code:
UPDATE doors SET lockpick=20,keyitem=20361 WHERE id=131
UPDATE doors SET lockpick=25,keyitem=20362 WHERE id=124
UPDATE doors SET lockpick=30,keyitem=20363 WHERE id=136
Pretty simple set of fixes.
Also, I looked into the issue where the pets of casters were at the zone line. As near as I can tell, there's nothing I can do about it. I went around the zone looking for missing pets and only found one guy with a missing pet. The pets also are not part of a spawn in the database, so deleting their spawn does nothing.
Sorry.
That should fix the doors for Befallen, though.
