[Server Database Editor]

That is correct, I am no longer updating this tool (for now at least). There has been many database format changes lately on both emulators which made updating more troublesome. Every new update breaks many features everytime and keeping things compatible between emulators has become much harder.  I would have to do a lot of refactoring to make this smoother, but... I unfortunately do not have as much free time as I'd like to start such a project.

How do I add monster skills? I try to right click but there's only "paste"

 

Adding them with a right-click "Add" menu wouldn't work out too well because mob skills do not have unique IDs. To add a mob skill, go in the "Mob Skills/Mob Skills2" tab, Edit > Add entry (Ctrl-N) and fill in the information. Alternatively, mob skills can be copy pasted across the application which can make this process easier :

• If you select another mob for instance, you can right-click its skills and use Copy, then use Paste on your own mob.
• If you select an existing skill from Mob Skills, you can copy it (with Ctrl-C) and use Paste on you own mob as well.

If you want, I could add the "Add" option, but it'll only create an empty mob skill and you'd end up having to fill in all the information yourself from the Mob Skill tab anyway...!
