Lovecraftiana – More Items & Monsters from the Cthulhu Mythos
Upon a distant plateau lies foul denizens of Leng.

While many horrors beyond our reaches have found their way into the material, other things creep into reality and bring chaos with them in more subtle ways.  Some lurk just beyond the veil, while others find others to do their bidding.  Whether they seek to destroy us or take over, eldritch powers are slowly becoming more pronounced.  It is unlikely that we’ll ever be ready for them. – Finnemin Cobblertoe, Halfling Archivist

Author’s Note: I wanted to make another contribution to the December ’17 blog carnival.  So, true to Doc tradition, here’s some more H.P. Lovecraft creations for 5E!  You can find more cosmic horrors throughout my blog via relevant tags like ‘lovecraft‘ and ‘cthulhu mythos‘.  Read more about the RPG Blog Carnival Blog here.


Magic Items & Artifacts.

Fiddle of Erich Zann (Cursed)

Wondrous item, legendary (requires attunement by a bard)

This fiddle quite simply looks off. The geometry is slightly off-center, the interior looks non-euclidean, the color scheme looks sickly and disgusting. Only a madman would have owned this instrument. And from its strings, an equally horrid tune plays. The music cannot be described as anything from this realm, but is none the less truly ghastly.

The Fiddle works as per the rules on Instrument of the Bards (Dungeon Master’s Guide Page 176), with some differences. The spell list is granted as follows: Dissonant Whispers, Tasha’s Hideous Laughter, Arms of Hadar, Confusion, Hunger of Hadar, Maddening Darkness, Crown of Stars.

Curse.  The first time the fiddle (whether as an implement for a spell, for any abilities granted from it or to play music), the user must make a (DC 15) Wisdom saving throw.  Upon failure, they receive a short-term madness effect.  This saving throw is made throughout the day until the user fails.  Upon failure, this will not happen again until the user completes a long rest.


Reanimating Reagent

Wondrous item, rare

A standard medical syringe and bottle contain a fluid that glows an eerie light green. Even in the dark, the ominous reagent shines through the shadows, as if a terrifying reminder of its power. When administered to a corpse, it is revived… but incorrectly so. It returns as an angry and vicious monster, only caring to destroy anything that reminds it of life. Some still retain sentience, but most are far gone and feral.

The bottle of the reagent has enough supply to have up to 5 uses.  The user simply sticks the syringe in the bottle to drain the appropriate dosage.  As an action, the user injects the solution into a corpse.  Nearly 1 minute after injection, the corpse is reanimated and brought back to full hit points, but also gain the Undead Fortitude quality as well as immunities to Poison damage and Poisoned condition of the Zombie.  However, their alignment changes to Neutral Evil.  In addition, they must immediately make a DC 18 Constitution saving throw.  Upon success, the character retains full control of their actions, if their death was recent.  If the corpse died more than a couple of days ago, they act like a typical zombie, except they can be influenced through Charisma checks.  Upon failure, the living dead immediately lashes out in a frenzy, attacking the nearest living creature.  While technically living dead, creatures revived by the serum do not count as undead for abilities relating to them, such as Turn Undead and Divine Smite.


The Necronomicon

Wondrous item, legendary artifact (requires attunement)

This eerie book is wrapped in a rough leather, akin to human skin.  The front of the tome even has a stretched human-like face on it, warped in an expression of eternal horror.  Inside its pages, you see illustrations of fiendish monsters, impossible aberrations and disgusting warpings of flesh and bone.  Its contents are filled with incantations, ramblings and grave warnings.  While a chronicle of dark things witnessed by the author, the tome itself has a dark surprise; it’s very much alive.

The Necronomicon is a book with a variety of spells and magical effects, at a price.  You gain the following benefits after reading up to 48 hours worth of time in total.

Unspeakable Knowledge.  When you spend the required time reading the Necronomicon, it gifts you with taboo knowledge.  You gain a +2 ability score bonus to Intelligence, but take -2 penalty to Wisdom upon completing the time required to read through it.  In addition, as long as you are attuned, your stat maximum for Intelligence increases by +2.  You are proficient in Intelligence (Arcana), (History) and (Religion) if you were not so already.  In addition, any checks related to knowledge of the cosmos, strange psychic phenomena, eldritch abominations and aberrations have a doubled proficiency.  As long as you are attuned to the Necronomicon, these effects remain.  If you are no longer attuned, these effects wear out 24 hours later.

Sanity’s Requiem.  When rolling for psychic damage, you may reroll any 1s and 2s, but must keep the end result.  In addition, you may temporarily increase the DC any spell involving charming, frightening, illusions or psychic damage by 2.  If the spell is concentration based or continuous, the DC adjustment remains as long as the spell is active.  When a creature takes psychic damage, you may cause them to make a Wisdom saving throw (DC 20) or take a level of madness as a reaction, once per long rest.  If the target has already gained a level madness within 24 hours, they take the next tier (short term, long term, indefinite).

Cosmic Communing. Once every 24 hours, you may attempt to commune with the dark forces of beyond.  The user must take 1 minute to enact the ritual and it lasts for 1 hour afterwards.  This effect works similar to Commune or Augury.  The DM, acting as an Old One may be contacted in this manner.  They’ll speak in a strange and alien tongue.  Should the user understand them, they’ll receive cryptic and bizarre messages.  These statements are ominous and hint at something horrid in the near future.  However, they also bestow insights upon the user.  In addition to gaining knowledge, the user gains a greater awareness of the environment around them.  For 8 hours after finishing their encounter with the Elder Being, they are counted as being under the effects of the Foresight spell.

CURSE. Curse of Eldritch Horror.  Upon attuning with the Necronomicon, the user begins to go insane.  They are haunted by disturbing visions of horrible creatures and inevitable dooms.  Dark revelations begin to make more or more sense to an increasingly worried mind.  The user automatically gains an indefinite madness effect, which cannot be removed while the curse affects the user and/or while the user is attuned.  Any spells that would ordinarily rid the effect fail in this case.  To make matters worse, sanity actively falls while attuned.  Every day after attunement, the user must make a Wisdom saving throw (DC 20).  Failure results in losing 1 point of Wisdom, thus making subsequent saves harder.  Alternatively, you may use the Sanity stat for both saving throws and damage.  Consult rules for Sanity and Madness within the Dungeon Master’s Guide.  Greater Restoration will allow the victim to receive one lost point of Wisdom/Sanity per casting.
