According to the D&D 5e Monster Manual, regarding destroying a phylactery, it says:
Destroying a lich's phylactery is no easy task and often requires a special ritual, item, or weapon. Every phylactery is unique, and discovering the key to its destruction is a quest in and of itself.
— p. 203, Death and Restoration
However, no further information is given on how this is typically done, or what is involved specifically.
I get that this is meant as a plot hook for the DM, and that the DM is meant to fill in the blanks as befits their story/campaign, and that the intention here is that different lich's phylacteries must be destroyed in different ways, rather than a one-size-fits-all method for destroying any phylactery.
However, it would be easier for me to come up with something if I had some examples to work with from existing adventures or additional lore on liches not included in the D&D 5e Monster Manual. Is there anything published in any edition of D&D that describes how to destroy a (specific) lich's phylactery?
