How to Edit/Add Items at Master Branch


I’d like to know, how to add a new item to the server, or edit an existed one. Since theres no longer an item_template table at the DB, I need to add it trough DBC files?
For example: items.dbc or items.db2?

Using hotfix database - you want to insert data to item, item_sparse, item_modified_appearance tables

Hi! What file in source code contains info about items at Master Branch? Like in itemdisplayinfo table in 3.3.5a?
