Sovereign glue is a fun magical item used in DnD. It forms a permanent adhesive bond between two objects. The glue takes 1 minute to set and cannot be broken once set.

Except … if one uses universal solvent, oil of etherealness, or the wish spell.

One key thing to note is that the glue only works on objects; not on creatures. You cannot glue two creatures together, but you can glue their armor together. 

There are lots of creative things a band of adventures can use the glue for (a ship is an object…). Keep in mind that the adhesive won’t break – but the glued objects possibly could.
