My search items is broken so I have a number that I need to find. If you could give me the location or name that would be awesome!

1. Display Cases

2. Altar of Spellmaking

3. Altar of Enchanting

Also, how do you get items to snap together? I.e. Alyeid ruin pieces? I've done it before but I can't figure it out....

display cases are under doors, don't know about the others. the easiest way to find out is to find one in the world and look it up (or just copy it).

turn on Snap to Grid and Snap to Angle.

They are under Activators.
