Hump Day Hazard: Disjunction Decay

magic itemsAncient tomes speak of an age when magic was feral, where magic-users wielded nearly unimaginable and insurmountable power—provided they survived their first forays into spellcasting.

One such power was that of disjunction, or the separation of magic into its most base elements. While this ability was harmless on its own—and, in fact, valuable to early practitioners of alchemy—some wielded disjunction like a weapon, stripping the magic from their enemies’ possessions with abandon…

The remnants of this power can be found in the eldest catacombs beneath the realm, where piles of disjoined magic items lie broken and discarded. As centuries pass, the sundered arcane essences of these items leak and congeal, creating an invisible aura of anti-magic. This hazardous phenomenon is referred to by adventurers as disjunction decay.

Disjunction Decay (Level Variable Obstacle)

Hazard (XP Variable)

A pile of decrepit items lies scattered across the floor, tarnished as if they had been dipped in several colors of dye.

Hazard A 4-by-4 square area is wreathed in an aura of anti-magic caused by the decay of disjoined magic items

Perception
No check is needed to notice the decayed items

Additional Skill (Arcana)
DC 10 + 1/2 hazard level—You deduce that the items were once magical
DC 15 + 1/2 hazard level—You recognize the nature of the hazard

Trigger When a creature carrying a magic item or artifact enters or starts its turn in the hazard’s area of effect, it attacks

Attack
No Action           Melee
0
Target
The triggering creature
Attack
Level + 3 vs. Will
Hit
The target cannot use daily powers granted by magic items of the hazard’s level or lower (save ends)
First Failed Save—The target cannot use encounter or daily powers granted by magic items of the hazard’s level or lower (save ends)
Second Failed Save—The target cannot use at-will, encounter, or daily powers granted by magic items of the hazard’s level or lower (save ends)
Effect
If the target is carrying an artifact, the hazard makes an additional attack; level + 1 vs. Will; on a hit, one artifact the target is carrying (target’s choice) has its concordance reduced by 1 (if this would reduce the artifact’s concordance to 0, it is destroyed and its owner takes limited high psychic damage by level)

Countermeasures
With an Arcana check (DC 15 + 1/2 hazard level) and a standard action, you can grant an adjacent ally a saving throw against the hazard’s effect (this saving throw is made with a +2 bonus)
Intelligent magic items automatically identify the hazard and grant their owner a +2 bonus to saving throws against its effect

Notes

When an artifact is destroyed by this hazard, the GM must secretly roll a d20, adding 5 to the result per artifact tier. If the result is 20 or greater, the event attracts the attention of a deity or other powerful beings who have an interest in or connection to the artifact.

Tactics

The power to disjoin a magic item’s essence is, to the relief of many adventurers, rare and largely forgotten. Few dungeon lords of any kind are adept in its practice, and even fewer dare take advantage of the lingering effects of such destructive spells.

A disjunction decay hazard can be found amid remote dungeons in any ecology, populated by any manner of denizens.

Kobolds do love traps and hazards, and Scott’s done a great job with them. I suspect we might see another hazard next week.

What I really love about this trap is how it so elegantly uses the 4e mechanics to make an anti-magic trap which isn’t completely binary. Losing _some_of the powers of magic items in an easy-to-adjudicate way is great.

Absolutely keep ‘em coming!
