Conclusion;
When wanting to add a given AA ability to a quest turn in, like the first note to the GM when you first create a character, follow the information below. I did this for Rangers giving them endless quiver, and the item received is now a bow. Obviously this can be customized to anyone needs.
Old code: Noted by "quest::"
Code:
$client->IncrementAA("AA_ID");
New code: Noted by "e.other:"
Code:
e.other:IncrementAA("AA_ID");
Where "AA_ID" you'll simply put the ID of the specific AA typically found in the "altadv_var" table of your SQL server. For Rangers Endless Quiver, the AA_ID is 205.
