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.
