Here are a few Items of Power, based on real world mythology:
Kusanagi, -1[-0]
It is what it is: A Sword, pretty simple. Weapons: 3
[-0]
Unbreakable.[+2]
One Time Discount: Swords are noticable.
[-2]
Channelling: Air[-1]
Invisible Edge: You may use Weapons to Control Air Spells.
The sword gained its name from the warrior Yamato Takeru, who was ambushed in a field of grass that was set ablaze. When he swung the blade, he found it allowed him to control the direction the wind blowed with each swing. Using this power, he was able to send the fire back at his ambusher, and gave it the name "Kusanagi-no-Tsurugi", or "The Grass Cutting Sword"
Notes: While in-universe Kusanagi's powers have been spoken for as a Sword of the Cross, I decided to make this in case someone wanted to have a non-Dresden Files setting, but still draw on myth and mythology. Same for Excalibur and it's Scabbard Below.
Excalibur -1[-0]
It is what it is: A Sword, pretty simple. Weapons: 3
[-0]
Unbreakable.[+2]
One Time Discount: Swords are noticable
[-1]
Marked By Power: It is more a symbol of Arthur's right to rule than a weapon.
[-1]
Mantle of the King: You may use Weapons to applies Aspects relating to your Authority.
Excalibur's Scabbard -2[-0]
It is what it is: A Scabbard, swords go inside it
[-0]
Unbreakable.[+2]
One Time Discount: Swords are noticeable, as are Scabbards
[-2]
Inhuman Recovery: Wounds given to those who used Excalibur where said not to bleed.
[-2]
Inhuman Toughness: Whoever owned the Scabbard was said to be protected against harm.
Notes: Again, while Excalibur and Kusanagi have more or less been spoken for in-universe, this is the version that's based on a more literal taking of the myths.
Seal of Solomon -1[-0]
It is what it is: A Ring, a snazzy one at that.
[-0]
Unbreakable.[+1]
One Time Discount: Rings are small.
[-2]
Divination: Said to be a gift to Solomon from god, it allowed him to call forth angelic spirits as advisors or to answer questions. While the spirits will try to answer the questions as best they can, they are ultimately still unwilling or unable to affect the process of Mortal Free Will, and thus may only give cryptic hints instead.
Optional:
-1 Holy Touch: It's a gift from God, why do you think this is here?
Notes: There are actually several versions of the Seal of Solomon, I went with the one where it was a gift form God. I also was unsure if it should be Summoning and Binding or Divination, but since it's ultimate purpose was to answer questions and provide knowledge, I went with Divination. The Holy Touch Ability is there because, well, lets face it; if you give a player a ring that was a gift from God, then you know he's going to want to punch a Vampire in the face with it and claim it satisfies it's Catch sooner or later.
Shoes of Vidar -0[-0]
It is what it is: A set of unbeatable shoes
[-0]
Unbreakable.[+2]
One Time Discount: Shoes are visible.
Thats... Thats it really. The God Vidar basically had a really awesome set of Shoes that were 'unparalleled'. Kinda drew the short end of the stick for that.
Notes: This one is here just because not every mythological item had awesome powers. Some were pretty tame. But then again, a clever player could figure out how to get an advantage out of an unbeatable set of shoes.
The Book of Thoth -2[-0]
It is what it is: A book, it's pretty old, be careful with it.
[-0]
Unbreakable. Or not.
[+1]
One Time Discount: It's a book, not hard to hide.
[-3]
Thaumaturgy: Said to contain knowledge of a vast array of Spells and Enchantments.
Notes: Wanted something that wasn't a weapon, you would be surprised at how hard that is to find.
The Tablets of Destiny - 5[-0]
It is what it is: A Tablet made of stone, it's pretty old, be careful with it.
[-0]
Unbreakable. Or not.
[+2]
One Time Discount: Big stone tablet, pretty obvious.
[-2]
Reality WarperSculpt Reality. You can always alter reality as if you were in your personal Demesne, though with slightly reduced effectiveness. This allows you to make declarations, maneuvers, and blocks related to the nature of the local reality with your Discipline skill. The duration of the changes created by this power is variable, but it's generally at least one scene.
Offensive Sculpting. You may use the world around you as a weapon. This allows you to make Weapon 0 attacks with your Discipline skill against anything within your line of sight. You may make spray attacks with this power. You may also attack entire zones with this power, although you suffer a -2 penalty to do so.
Improved Sculpting [-1]. Your Offensive Sculpting attacks are now treated as Weapon 2. Furthermore, you need take only a -1 penalty to attack a zone with Offensive Sculpting.
Powerful Sculpting [-1]. Your Offensive Sculpting attacks are now treated as Weapon 4, and any scene aspect you place with Sculpt Reality is automatically made Sticky. Furthermore, you need not take any penalty to attack a zone with Offensive Sculpting.
Counter-Conceptual Interposition [-1]. You may use your Discipline skill to defend against physical attacks.
Reality Binding [-1]. You may use this power to grapple targets within your line of sight, using the normal grappling rules to do so. Substitute your Discipline skill for your Might skill when grappling someone this way.
Create Hazard [-1]. When attacking a zone with this power, you may take an accuracy penalty (before rolling) in order to extend the duration of the attack. For each point of accuracy sacrificed this way, the attack is reapplied at the beginning of another exchange. You may take actions to extend this effect as though you were an evoker extending an evocation.
Alright, here is what I have so far. I would include more, but it's almost 11PM where I am, and my brain needs rest.
Not that I'm going to bed any time soon...
