A favorite RPG blogpost of mine is “On Resurrecting the Quantum Ogre and Having Him Over for Tea” (https://hackslashmaster.blogspot.com/2011/09/on-ressurecting-quantum-ogre-and-having.html).
In tonight’s D&D session, the party finds a crown they know must be destroyed. After two attempts with what they have on hand, the DM speaks up to remind us of a special hammer and anvil encountered in a session almost two real months ago. Bravo!
Time is the thing we all have the least of. That reminder saved time and had zero downsides.
