Since the last release, changing staves projectiles involves the new toolbox abilities players can activate via the Forgesmith's tools quickitem.
There is only one ability involved in this modification :
This ability is unlike most the others. Activating the ability triggers the usual container where players have to place their staff. The current projectile type will be indicated by a crystal automatically created in the container. Players can change that crystal, and the staff actual projectiles, by drag & dropping an item - shown below - as many times as they wish.
Simply closing the frame will apply the modification. According to the configuration, a dummy will appear to try the new projectiles out. (option enabled by default)

Until a proper guide is written, please watch the example video available above.
