All of these items hold great amounts of power and are intended as the focus for powerful villans to try and take over the world. Many have multiple components above the item itself that are required for it’s use and blocking the villian’s access to these can form part of the adventure, even if the PCs fail to keep the villian from obtaining the main item.
Many items are inspecific about how far their effects may be felt - this is deliberate as individual GMs should choose this as appropriate for their campains.
These items are not intended as random loot or even as things a PC party should have. If the PC’s do have them, efforts by other to obtain them would be unceasing, and the very nature of the items may dissuade their use. No good should come of owning these.
That said, bring on the Power Overwhelming!

1) Sargio’s Defoliator
Appearing a small ballista bolt, this ‘bolt’ is actually an arrow used by a god from a long-dead pantheon. Some sages theorize it was a weapon crafted by Loki to slay the world tree. Why it was never used escapes them.
The spear has a divine-level anti-plant effect. When driven into the soil point first, an ever widening circle of destruction radiates out from the point, killing any plant material. Perfect for holding a kingdom’s food supply for ransom. Any who bear this device are cursed so any plant-based materials they touch crumbles to ash. The final size of the spear's destructive circle is of course up the GM. If used as a weapon vs plant-based creatures, it is incredibly deadly and is considered a 'slaying' item.
2.) The Abyssal Key
A massive key, 2’ length, weighing 20lbs, was forged from the bones and horns of demon-lords. When used with a massive portal - carefully built according to documents found in powerful books of evil knowledge, it will open into the realm of demons and allow them to flood into the world. The applications of this item for villains are obvious. Mortals touching this item are subject to Effects of Touching Powerful Evil Artifacts.
Made from the tears of a bound goddess, this magical wine has the power to charm or dominate any who imbibe even the faintest quantity. Once affected, it remains dormant until the victim hears a special magical phrase, upon which they will be magically bound to the speaker. Enterprising villans could drop this into the water supply of an important city..
The hammer of a war-god avatar, this massive weapon must be wielded by a giant or other supernaturally strong being. When struck against the ground, a massive seismic wave will propogate outward from the wielder subjecting all in its wake to a massive earthquake. This quake is stong enough to shatter castle walls.
A ruby of immense size, this stone was once the eye of a diety of war. When properly commanded by long lost rituals, the huge gem will rise into the sky, glowing brightly. Visible for miles, all who look upon it in its full radiance will be filled with intense homicidal rage.

A weapon of war created by an extinct race, this rat appears normal but is a similacrum - beneath it’s mangy fur is a body of bronze. Commanded by words in a lost language, wherever it goes a viralent and lethal plauge follows. The cure is similarly obscure.
Perhaps the product of another universe or time, this vessel appears as an early Tall ship, but is made of iron from keel to spar. The sails are a battered canvas but are nearly indstructible, but in truth do little to move the ship - the ship is able to move even with no winds.
The ship is powered by life force, requiring regular sacrifices to ‘charge’. The victims are cast in front of the vessel as it moves, it’s razor sharp bow bisecting them. The ship may initally be missing key components and the ritual to power it would also require research by would-be users.
The ship has no built in weapons aside from it’s bow, which can easily cut even large wooden ships in twain.
This huge cauldron is a powerful transformational device once filled with the correct brew of dreadful ingredients. Once active, any living being immersed in the liquid will be transfromed into an infernal form.
This bronze anchor will stop the motion all water within miles of where is it dropped. When dropped into a river, water will stop in the radius, the river downstream of the area of effect will run dry, and upstream, flooding will occur as the water will not enter the radius of effect.
