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!
Honestly, if I were a high-level caster in DnD setting, I would only use Alarm. What could possibly be a better defense than myself? And if I’m not alive to recast the alarm, what do I care for the fate of my lab?
Would probably take inspiration from Marvel with The Collector (I think?) And show them buck wild shit with no defenses at all. If they want to rob someone who puts no locks on a lab full of expirements on undead dragons and crazy artifacts just sitting on tge wall, go for it.
That is the kinda DM I am though lol
For one powerful, arrogant wizard it’s perfect
