Integrating Adventurer Conqueror King System II (ACKS II) with the legendary, chaotic, and maximum-gonzo DNA of Dave Hargrave’s Arduin Grimoires- d100 treasures & relics table from the Arduin rpg

 In Dave Hargrave’s Arduin Grimoire series (Volumes I–III and The Arduin Adventure), random treasure generation subverts standard fantasy tropes. Hargrave mixed high fantasy with sci-fi, cosmic horror, and weird fiction. This blog post picks right up from Integrating Adventurer Conqueror King System II (ACKS II) with the legendary, chaotic, and maximum-gonzo DNA of Dave Hargrave's Arduin Grimoires - Converting Arduin's Welcome to Skull Tower (1978) To ACKS II

Below is an authentic d100 Random Artifacts, Tech-Relics, and Exotic Treasures Table synthesized directly from the classic Arduin Grimoire tables and items—formatted for d100 random rolls in any classic OSR, ACKS II, or campaign setting.

Campaign Rules for Arduin Loot

• Cross-Genre Identification: Characters with sci-fi technology (laser pistols, power cells, vibro-blades) who do not possess a relevant proficiency (e.g., Engineering, Ancient History, or Arcane Artifice) must make an Intelligence Check when first trying to operate the item. A failed check indicates a mechanical jam, while a roll of 1 indicates a catastrophic battery explosion.

• XP for Sci-Fi Relics: In gold-for-XP systems (like ACKS II or classic B/X), high-tech loot can be sold to sages, mages, or collectors for the full GP value listed above, converting directly to character Experience Points.

Adapting North West of Earth By C.L. Moore - Orbital Decay (MicroRed version) From The Red Room & The New Flesh Rpg - D100 Random Solar System encounter table based on North West of Earth By C.L. Moore

 

C.L. Moore’s Northwest of Earth collection—featuring her iconic space-faring rogue Northwest Smith—blends planetary romance, cosmic horror, dark decadence, and raygun pulp. In Moore’s 1930s Solar System, Mars is a dry wasteland of ancient dead gods, Venus is a sultry jungle ringed with sinister matriarchal fortresses, and Jupiter’s moons hide ethereal siren-entities.

Below is a d100 Random Solar System Encounter Table crafted in the rich, hypnotic style of C.L. Moore’s Weird Tales classics (Shambleau, Black Thirst, Dust of Gods, Julhi, The Cold Gray God, Yvala, Lost Paradise, and The Tree of Life).
