Delirium (drakenheim)

Delerium is a magical mineral left behind by the meteor that
struck Drakkenheim. It appears in geode clusters of translucent,
sharp-edged crystals that reflect octarine light. The
eldritch stones softly hum in dissonant tones, and glow brightly at
night or when exposed to magic. Deposits are found throughout
Drakkenheim, often fused into stone streets and buildings like
crystalline moss.
A typical delerium fragment is about the size of a finger.
Crystals may be fist-sized or slightly larger, and geodes may
be as big as a pumpkin. Massive clusters might grow taller
than an average human.

Delerium Properties
All delerium samples have the following traits regardless of size:
h Immune to necrotic, poison, and psychic damage; as well
as bludgeoning, piercing, and slashing damage from nonmagical
weapons.
h Resistant to acid, cold, fire, and lightning damage; as well
as slashing and piercing damage from magical weapons.
h Vulnerable to bludgeoning damage from magical weapons.
h Unless contained within an antimagic field, delerium
shatters and crumbles into worthless ash when reduced
to zero hit points. However, delerium geodes release a
random Arcane Anomaly when destroyed (see below).
Delerium Hazards
When a creature touches delerium without protective
gear for the first time on their turn, or ends their turn in
bodily contact with delerium, they must make a DC 10
Constitution saving throw or take 1d6 necrotic damage and
gain 1 Contamination Level (see Appendix C).
Delerium Harvesting
Delerium found in Drakkenheim is usually fused into the
ground or stone buildings, and may be carefully extracted
using handheld mining equipment such as shovels, picks,
hammers, and chisels. Consult the table to determine how
long it takes characters to harvest delerium deposits of various
sizes. Lacking proper equipment, extraction takes ten times as
long. Massive clusters are impossible to extract without heavy
equipment or powerful magic.
Uses for Delerium
Delerium has vast arcane potential. Beyond trade, delerium
crystals are used for several purposes:
Spell Component. Delerium may be used as an arcane
focus or material component for any spell on the apothecary,
sorcerer, warlock, or wizard spell list. When casting a spell which
requires a costly material component, a spellcaster may instead
use delerium of equivalent value to the required cost.
Magic Items. Delerium is an exceptional material for creating
magical items of all kinds. Any magic item described in the Core
Rules could be made with delerium. Fragments, shards, crystals,
and geodes may be used to make uncommon, rare, very rare, and
legendary items respectively. At the GM’s discretion, characters
who can cast 5th-level spells or higher may learn techniques to
craft magic items of their own during their downtime.
Stable Delerium. The process for crafting magic items
with delerium renders the crystals stable. Unless otherwise
specified, characters do not take damage nor risk contamination
when they touch or handle stable delerium. Stable delerium is
damaged and destroyed in the same manner as a normal magic
item of its kind.
Delerium Dust. Delerium dust is made by grinding the
crystals against one another to create a fine powder. This milling
process is extraordinarily hazardous unless performed within an
antimagic field. Delerium dust can be used in alchemy, as a spell
component, a reagent for brewing potions, or mixed into inks for
spell scrolls.
Improvised Weapons and Ammunition. Delerium
fragments may be used as ammunition for a sling or fashioned
into a makeshift club. Such weapons and ammunition deal an
extra 1d6 necrotic damage, and humanoid creatures struck
must make a DC 10 Constitution saving throw or gain one
Contamination Level. Delerium used as ammunition in this
way is destroyed.
