I would like to use a wizard as the enemy. I've done that before but this time is different: his class level will be above the group's level. As with any other wizard in the world he has to use a spellbook.

This spellbook is my problem because in this specific case I don't want it to be part of the reward. This wizard's spells list will be significantly different from the party's wizard. I usually let him learn some spells this way but in this case it would be too much.

This wizard knows the party and seeks revenge on them so it makes perfect sense that he has prepared things to avoid his spellbook falling into their hands if his plan fails.

How can my NPC wizard ensure that his spellbook is destroyed when he dies?

I plan to use a 10th level wizard with access to 5th level spells but he is part of an organization that can have access to almost any resource.

As for my game sources I use the 3 core rulebook, volo's guide, xanathar guide and mordenkainen tome.

    \$\begingroup\$ A good point is made by @Rubiksmoose in one of the answers; what if the party capture rather than kill the wizard? Do you just want this on a kill? \$\endgroup\$

    \$\begingroup\$ @SeriousBri due to the previous encounters they had with this wizard I'll expect a kill, but I'll think also about that. \$\endgroup\$

Thanks to the resources of his organization, this wizard has a contingent fireball cast upon the spellbook. (This makes use of the 6th level contingency spell). The contingency spell is keyed to go off upon his untimely death. (The fireball can be cast at 3rd, 4th, or 5th level and still be used with the contingency spell).

The fire ... ignites flammable objects in the area that aren't being worn or carried.

The result utterly destroys the tome and provides a 'last laugh' from the fallen mage.

Spell references:
Fireball (PHB p. 241-242)
Contingency (PHB p. 227)

    \$\begingroup\$ I think this is a very good answer. Note that this could have the unintended side effect of also killing the party if they happen to be within range of the blast and unfortunate in saving/having low HP. Also note that this particular wording would require them to kill the wizard which the party (depending) might not do. \$\endgroup\$

    \$\begingroup\$ Did explosive runes make it into fifth edition? In earlier editions, it didn't have any caveat protecting the page it was cast on from the damage dealt by the spell. \$\endgroup\$

    \$\begingroup\$ Contingency only targets the wizard that cast it, so if he's not actually carrying the spellbook, it won't work. It seems rather fatalistic for a wizard to use contingency to get revenge on whoever kills him rather than to prevent his death, but that's his business... \$\endgroup\$ Jul 8 '18 at 21:26

Glyph of warding

A glyph of warding placed on an object can hold a spell. A fireball will burn up a flammable object, such as a spellbook, in its area of effect. The PCs could theoretically defeat the glyph by dispelling it, and they might be able to detect it with an Investigation check, as described in the glyph of warding spell description. Compared to contingency, this has the advantage of not taking up the wizard's single contingency option. It has the disadvantage of requiring the warded object to remain in one location, but that might not be a problem for this wizard.

Leomund's secret chest

A wizard doesn't need his spellbook to cast spells, only to change the ones he has prepared (or cast rituals). A wizard can safely store his spellbook, or a variety of other valuable items, on the Ethereal Plane using Leomund's secret chest. Only the wizard who owns the chest can find it, so this is reasonably secure. If he dies, the chest and its contents aren't technically destroyed, but they're going to be awfully hard to track down.

Drawmij's instant summons

A similar effect can be achieved with Drawmij's instant summons, which allows for faster recall, but with a higher cost and less overall convenience. Since only the wizard who cast the spell can use the key, if the wizard dies, the protected item remains hidden (say, buried under a few hundred tons of granite).

A semi-mundane device

Some wizards might find it amusing to protect their spellbook with some sort of mechanical trap in their lair. Suppose a clockwork mechanism triggers a mechanical shredder that will destroy the spellbook if it's not wound every day - and the entire apparatus is thoroughly hidden (possibly accessible only via magical means of some sort). The wizard who inhabits the lair can easily wind the clockwork, but by the time any invader figures out what they need to do, it would be too late.

"A wizard did it"

Since the wizard in question has unusual spells, he could presumably have a spell designed just for this purpose. Your creativity is the limit, but what comes to mind is hiding the master copy of the spellbook in a place where only the owner knows where it is, and then having a spell to summon an illusory copy on demand.

    \$\begingroup\$ Drawmij's Instant Summons allows you, the caster to retrieve the item; others can't. So it's an even more secure option than you imply (if rather costly for the wizard). \$\endgroup\$ Jul 9 '18 at 8:14
  • \$\begingroup\$ Glyph of Warding breaks if moved more than 10ft. from where it was cast so if the wizard wants to carry his spellbook with him Glyph of Warding will not work. \$\endgroup\$

    \$\begingroup\$ Having the wizard create a spell that self destructs the spellbook if anyone else touches it sounds like a perfect evil wizard thing to do. It might even be fun to let the party wizard recover that spell and no other. \$\endgroup\$

  • \$\begingroup\$ Re: "Semi-mundane device." Go look up how Yagami Light protected the Death Note early on in the anime by the same name...he had a very specific way he had to retrieve it, and it would be obliterated if he didn't retrieve it in that way. Admittedly, there's the chance the party will notice the trap and dismantle it... \$\endgroup\$ Jul 20 '19 at 19:20

The NPC Wizard need not have a spell book; use a Volo's Guide NPC

Using either the Conjurer (p. 212), the Enchanter (p. 213), or the Transmuter (p. 218) spell casting NPC, each of whom can cast 5th level spells you have a ready made wizard-like opponent already built.

If you look at the NPC description, these NPCs are not equipped with a spell book. They have spellcasting as an NPC/Monster feature, have spells known/prepared (MM, p. 10), and behave much as a PC wizard does but are not in fact wizard PCs and could be treated some ways (mechanically) as Sorcerers. They have a default set of spells prepared (like a Sorcerer does) but you can adjust them to get the caster to be set up just the way you need them to be (MM, p. 10). This also allows you to tailor their spells to contrast to what your party's wizard has available.

For another example, albeit at higher level, see the Archmage NPC in the MM.

It's not the only way to solve this problem, but they are premade for the kind of challenge you are preparing. Since you have Volo's Guide, I figured I'd point you to a resource that you use at your table, and that you have already bought and paid for. 8^)


  1. Tweaking the Challenge Rating. If you feel that those aren't hard enough NPC opponents, you could raise the CR a bit and have them deal with an Evoker, who can cast up to 6th level spells. (p. 214) To keep it "5th level spells" as a limit you can have the Evoker upcast lower level spells with a 6th level slot ... but that's perhaps more fiddly than you want to get for this challenge / encounter.

  2. Players can surprise you. A second advantage of this approach is that if your party chooses to capture, rather than kill, this wizard there still isn't a spell book for them to loot (if that remains a key element of your intention for this encounter).

  3. Treasure Tweaking. You can still leave a scroll or two as loot for the party's wizard to benefit from without there being an entire spellbook to copy spells from as a reward from this encounter.

Don't worry, use your imagination. A wizard doesn't need his spellbook to use spells, just to preparate them daily, if you wanted you could actually tell the party he hasn't the spellbook with himself. Maybe he has it in a secret place, maybe it is guarded in another plane only accessible by the enemy wizard. It's up to your imagination. Also, you can put a false spell in a false spellbook, something like "Anyone who reads this suffers a Disintegrate", maybe written upside down, it's a funny way to troll players (maybe while they hear a last laugh of the dead wizard pre-recorded and activated with the disintegrate).

If you don't want to hide the spellbook, you always make it to be in a sort of code only known by the wizard.

Note: As said before, the "Anyone who reads this suffers a Disintegrate" was just an example, you can use the spell you like the most.

    \$\begingroup\$ How is it a player's avarice to want to recover spells from a fallen enemy wizard's spell book? That's part of how the wizards gain new spells in this edition. \$\endgroup\$ Jul 7 '18 at 15:06

    \$\begingroup\$ Just a way of speaking. It can result in a funny moment for the table, imagine it, the wizard takes the spellbook and tries to read some kind of strange language, the DM makes him throw an investigation check, in a failed throw, the wizard takes disintegrate, if he succeeds, he obtains a one-use disintegrate, which can be used to troll a powerful enemy. Also the words "any one who reads this" give a quite funny situation. \$\endgroup\$

Write the spellbook in code

The wizard uses a personal cipher when recording spells in his spellbook, and the players have no way of translating it. Comprehend langues doesn't translate codes, and the wizard didn't teach his cipher to anyone.

  • \$\begingroup\$ While this may work to keep the players from getting the spells, telling them they have no way of deciphering the book they are holding can be off putting. \$\endgroup\$
    – FenrirG
    Jul 9 '18 at 10:48
  • \$\begingroup\$ I like this because this can easily be tuned - for example, the cipher might be tedious to use so the Wizard only bothered to write his most potent spells down in that fashion, so there might still be a couple of lower level spells the PC spellcasters can learn from it. \$\endgroup\$

    \$\begingroup\$ @FenrirG Use it as a quest hook, then! They find the spellbook in an unreadable code (or at least the good parts are, per @Cubic). They're bummed. Later, they intercept a letter in the same code! Instantly you've tied this wizard in with whatever other plot thread, and given them a lead on finding a way to read the spellbook. That's player catnip. \$\endgroup\$

Taking the lead from a Phoenix Sorcerer UA

You could homebrew a PhoenixBorn Wizard. When he dies his body erupts in flames rendering everything to ash. This has the added benefit of being able to resurrect this wizard if you want to later.


You cannot do this

If the Wizard has a spellbook, there is no sequence of protections you can place upon that spellbook that will definitely render it unavailable to the party wizard without it also being unavailable to the NPC wizard pre-death.

You cannot with 100% certainty, barring outright cheating, prevent the party from just tailing the wizard to the spellbook beforehand, or using social skills and disguises to gain access, or any number of other ways of bypassing whatever protections you give the book. There is no protection that doesn't have a way around it, and so it is always possible, however unlikely, that the PC wizard ends up with the book intact or you reveal the railroading as obviously unavoidable. If you can't deal with the PCs somehow gaining access to something, you need to not put it in your game or be willing to own up to the fact that the reason they can't have the thing is GM fiat.

That's not to say you can't have an NPC spellcaster casting 5th level spells without including a spellbook, of course. But if you put a spellbook into the game you either have to accept the PCs may find a way to keep it or else just tell them "You can't have the spellbook because that would be too good so we have to come up with some excuse as to why that doesn't work".
