Ravenous Bugblatter Beast of Traal
Traditionally in D&D, even the most powerful of artifacts, created by the gods themselves, have ways to be destroyed. I remember a chart from one of the TSR editions of D&D, with entries like "crushed under the heel of a humble ant".I'm thinking of a way a Lich would protect its phylactery. Seeing as they're powerful spellcasters, and immortal so long as their phyllactery is intact, what would they build it into so that it couldn't be ruined?
Adamantine?
I mean, what is out there that can't be overcome? Other than plot, i guess (and clever players foil that all the time)
Just like The One Ring has it's weakness, I think everything in D&D is possible to break, even if it takes an epic quest.
Though to talk about something hard to destroy, in one game I ran in a different edition (well, a d20 game called 13th Age), the Lich King's phylactery was an entire floating city left over from Ages past when he was the Wizard King. Stopping him from coming back by smashing the city was a century long plot from the Elf Queen. That city was the jewel of the human empire and the center for magical study for the entire kingdom, and not known to be the phylactery to most.
