Integrating Adventurer Conqueror King System II (ACKS II) with the legendary, chaotic, and maximum-gonzo DNA of Dave Hargrave’s Arduin Grimoires - Random Fey & Fairy Encounters

 Here is a d100 random encounter and prompt table designed specifically for the Adventurer Conqueror King System Imperial Imprint (ACKS II). This 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 The Techno PC Class To ACKS II Part II

Because ACKS II emphasizes realistic sandbox domains, economic scales, and explicit monster behaviors (such as raiding, lair distribution, and morale), this table goes beyond just names. It balances the classic BX-style fey (Sprites, Pixies, Dryads) with the folklore-heavy, dark, and opportunistic tone of the Auran Empire setting.

Entries include Numbers Appearing (NA) for Wilderness encounters, Activity/Hook contexts, and Treasure Types (TT) scaled to ACKS II hoard expectations.

3 Quick Fey Rules for ACKS II Judges

1. Iron Vulnerability: All creatures rolled on this table take an extra +1 point of damage per die from weapons forged of cold iron (non-alloyed, worked without heat). High fey (Sidhe, Hags) cannot cross a line of pure iron filings.

2. The Glamour & Market Value: Fey treasure (Treasure Types noted above) often looks like leaves, acorns, or river stones until brought out of the forest or past running water, where it reveals its true silver, gold, or gem value.

3. Domain Impact: If a Fey encounter results in a hostile interaction within a PC's Domain, it lowers the Land Investment stability or reduces the peasant population's morale by 1 point due to "the faerie blight."

Integrating the Arduin Cycle with ACKS II means shifting away from whimsy and moving directly into the bizarre, high-lethality, techno-magical, and trans-dimensional gonzo-fantasy that David A. Hargrave pioneered.

Arduinian fey are not just mercurial nature spirits—they are often radioactive, cybernetically altered, extra-planar refugees, or ancient genetic experiments from the Pre-Cataclysmic era. They carry plasma-burned weapons, possess brutal mind-blast capabilities, and their hoards feature ancient tech-artifacts alongside raw gems.

Here is a d100 random encounter table built for ACKS II wilderness or dungeon sandboxes, featuring custom Numbers Appearing (NA), Arduin-flavored Sandbox Hooks, and Treasure Types (TT) adjusted for ACKS II hoard value (including Arduin tech/magic equivalents).

3 Arduin-ACKS II Integration Rules

1. The Magico-Technical Hazard (The "Arduin Factor")

Many high-tech items found in Arduin fey hoards (such as blasters, sensory visors, or energy shields) require power cells. If a PC attempts to use a tech item without the proper Knowledge (Ancient Tech) proficiency, any attack roll or activation roll of a natural 1 causes a Technical Catastrophe:

Catastrophe: The item explodes or leaks radiation, dealing 3d6 damage to the wielder and destroying the item permanently.

2. Cold Iron vs. Alloyed Steel

While traditional ACKS II fey are vulnerable to cold iron, Arduin fey have adapted. Standard cold iron deals normal damage to them. However, they are highly allergic to Pure Titanium or Depleted Uranium weapons (+3 damage per die), which are occasionally found in Techno-Class arsenals or ancient ruins.

3. Domain Contamination (Market & Stability)

If an Arduin Fey encounter turns bloody within a PC’s domain, the magical/radioactive fallout is severe.

• The hex where the battle took place becomes Blighted for 1d4 months.

• Any agricultural income from that hex is halved, and the Domain's Civilization rating temporarily decreases by 1 level due to peasant panic over "the glowing rot."

To seamlessly drop Hargrave’s gonzo, high-tech Arduinian flavor into the structured, gold-standard economy of ACKS II, these items are mapped directly to standard ACKS II Treasure Type (TT) categories.

In Arduin fashion, magic and technology bleed together. Items that function as traditional magical gear specify their ACKS II equivalent, while pure tech items list their gp value for market integration and domain hoarding.

d20 Arduin Techno-Fey Treasure Table

d20	Item Name	ACKS II Equivalent / Mechanical Effect	Value / Hoard Class
1	Vibro-Spike Dagger	Functions as a Dagger +1. On a natural attack roll of 19 or 20, the high-frequency vibration bypasses mundane armor, dealing max damage. Requires a minor chemical cell every 50 strikes.	1,500 gp / Class II
2	Phasing Displace-Cloak	Functions as a Cloak of Displacement. Once per day, the user can purposefully activate the cloak to step through a solid wall up to 3 feet thick (Save vs. Blast or get stuck, taking 2d6 damage and shunting back).	4,000 gp / Class III
3	Rad-Purge Stim-Hypo	A pneumatic injector. Instantly cures any mundane or magical radiation sickness, neutralizes level-1 or level-2 poisons, and heals 2d4+2 hit points. Single use.	400 gp / Class I
4	Nano-Weave Elven Mail	Functions as Chainmail +2 but weighs less than a standard cloth tunic (Encumbrance: 0). It cannot be destroyed by mundane acid or rust monsters.	6,000 gp / Class IV
5	Plasma-Core Lantern	Casts a blinding, stark-white cone of light up to 120 feet. Can be overcharged once per day to fire a Plasma Bolt (3d6 fire/electricity damage, 30-foot range, requires attack roll).	1,200 gp / Class II
6	Chrono-Synced Pocket Chronometer	A ticking, brass-and-obsidian device. Grants a +2 bonus to the party's Evading Wilderness Encounters checks because it predicts local space-time anomalies.	800 gp / Class I
7	Neuro-Whip of the Seelie Court	Functions as a Scourge +1. On a successful hit, the target must pass a Save vs. Paralysis or be wracked with psionic feedback, suffering a -2 penalty to all saving throws and attack rolls for 1d4 rounds.	3,500 gp / Class III
8	Grav-Anchor Boots	Heavy, metallic boots lined with micro-gyros. The wearer cannot be knocked prone, tripped, or pushed back by wind or telekinesis. Grants a +4 bonus to saving throws against falling damage.	2,500 gp / Class II
9	Holocron of the Ancients	A glowing, floating fey crystal pyramid. Functions as a Scroll of 3 Spells containing random Level 1–3 Mage spells, but it projects them as holographic data streams. Can be transcribed into a spellbook.	Variable / Class II
10	Bio-Scanner Goggles	Grants the wearer Infravision out to 90 feet and allows them to see the exact current hit point total of any creature within 30 feet by reading their biometric aura.	3,000 gp / Class III
11	Melt-Core Grenade (x3)	Can be thrown up to 40 feet. Explodes in a 10-foot radius. Deals 4d6 fire/acid damage to all targets (Save vs. Blast for half). Completely melts mundane locks or iron doors.	1,500 gp / Class II
12	Starlight Mono-Shield	Functions as a Shield +1. When active, it projects a thin, hummed plane of hard-light. Once per day, it can completely absorb a single spell targeted directly at the wielder.	4,500 gp / Class III
13	Psy-Dust Pouch	Contains 1d4+1 doses of iridescent powder. Blowing it into a target's face forces a Save vs. Spells at -2. Failure causes the Charm Person effect, but the target's eyes glow faint neon blue.	1,000 gp / Class II
14	Cybernetic Sprite-Wing Graft	A jar containing delicate, chrome-and-gossamer wings. A skilled chirurgeon or techno-mage can graft them onto a humanoid PC. Grants permanent Fly (as the spell, but mechanical movement) at the cost of permanent -1 Constitution loss from the cyber-rejection.	12,000 gp / Class V
15	Anti-Matter Disintegrator Pistol	A sleek, white plastic firearm with 1d6 shots remaining. Range 60 feet. Requires an attack roll using the Crossbow weapon proficiency. Deals 5d6 disintegrating damage on a hit (no saving throw, ignores all non-magical armor). Cannot be reloaded.	8,000 gp / Class IV
16	Synapse-Booster Collar	When worn, this spiked chrome band raises the user's Intelligence or Wisdom score by +1 (up to an absolute maximum of 18). However, the intense neural overclocking causes them to take an extra +1 damage from all psionic or psychic attacks.	7,500 gp / Class IV
17	Zero-G Float-Pack	A bulky backpack that can be engaged for up to 3 turns per day. It neutralizes the wearer's weight entirely, allowing them to levitate, walk on water, or bypass pressure plates and pit traps without setting them off.	5,000 gp / Class III
18	Omni-Key Data Spike	A glowing, silver needle-key. When inserted into any mundane lock, complex mechanical trap, or ancient tech-terminal, it automatically unlocks or disables it. The spike breaks after 1d3 successful uses.	2,000 gp / Class II
19	Vortex-Trap Matrix	A heavy, metallic cube. Can be thrown to the ground to cast Web, but the "webs" are actually localized, miniature gravitational singularities that pull targets toward the center.	3,500 gp / Class III
20	Star-Sidhe Plasma Greatsword	A massive hilt that ignites into a 4-foot blade of blinding stellar fire. Functions as a Two-Handed Sword +3. Deals double damage to Undead, Demons, and Outer Horrors. Illuminates a 60-foot radius when drawn.	18,000 gp / Class V

3 Rules for Handling Arduin Tech in the ACKS II Economy

1. Selling the Tech: Traditional markets in the Auran Empire don't know what to make of these items. If sold in a standard market, they fetch only 25% of their gp value as curiosities. To get full value, they must be sold in a major metropolis, to a high-level Mage guild, or to a dedicated Techno-Archaeologist NPC.

2. Identifying the Gear: Magic identification spells (Analyze) will reveal the magical equivalent properties of an item, but won't reveal technical limitations (like chemical battery depletion or explosive malfunctions). That requires the Knowledge (Ancient Tech) proficiency.

3. Domain Construction Hoarding: If these items are placed within a PC's personal stronghold vault, their strange, lingering chronal and planar radiation acts as an accidental deterrent. The domain gains a +1 bonus to its Security rating against espionage or assassination attempts per 10,000 gp value of Arduin tech stored within the central keep.
