Generic high-fantasy setting (d&d 5e if you want to use specific spells), what security or defences would mages use to secure the place where they keep all their magical stuff? I’m thinking decoys, reinforced and hidden location, guards (hired or summoned), locks (both magical and mundane), booby traps, and spells to discourage or confuse passing snoopers.
Also it’s going to vary depending on the resources of the wizard and of the players. Is this an independent student wizard protecting their studies that a low-level party could reasonably break into, or is it the king’s secure vault of confiscated magical horrors that’s a final boss for the campaign?
I’m looking for ideas for fun obstacles, and critically that the players can’t just sidestep with a single low-level spell!
Artifacts? In a museum, in the"lost and found" box. I tend to go with the wizard that is a bit careless over the super planned one.
The box may or may not be a mimic.
Research room: Wizard Itor uses the back room of his office. The front room contains mops and cleaning supplies (some very magical). The door is even labeled “Jan Itor Supplies”
The door is also a mimic.
The room is also a mimic
The mimic is not a mimic, but is doing its best
I do love a good “hidden in plain sight”
