Phronesis, Gauntlet of Odessa

Description

A surprising mixture of materials, these fingerless gauntlets have leather joints and gloves, but the majority of the arm is guarded by what appears to be parchment. The leather is embroidered with purple thread shaping out glyphs that match the enchantments written in purple inks all over the arms.
 

Mechanics

Charges

Phronesis has 25 charges, and regains 3d8+1 charges each dawn. These charges may be used for various purposes, listed below.
 

Arcane Mark

You may prepare a number of additional spells from your spellbook each day equal to your Intelligence Modifier. These spells may be up to 9th Level. When you do so, you trace out runes and glyphs either as tattoos upon your own arms, or as markings upon the gauntlets.
  As an action, you may transfer one of your marks to a willing creature you can touch. You may transfer any number of these spells to any number of separate individuals this way, though each transfer requires an action. When transferred, the mark appears as a tattoo upon their skin, or a glyph upon a piece of their equipment. A spell transferred in this way is removed from your prepared list.
  A spellcaster with one of these marks may cast the spell inscribed upon them as if they had prepared it themselves, using their own spell slots, spellcasting ability, DC, and to hit rolls to do so. Once the spell is cast, the corrosponding mark disappears.
  When a creature you can see within 120ft uses a mark you have bestowed upon them (to cast the spell or activate your Infusions of Power feature), you may use your reaction to counter the activation, having it be expended without actually triggering the feature or spell.
  Upgrade - Share multiple marks with no limit on spell level. Protection against friends being mind controlled and using marks against you.
 

Binding Grip

As part of a short or long rest, you may bond a number of weapons or other hand-held items equal to your Intelligence modifier to this item as long as they are within reach during the entirety of the rest.
  While an item is bound in this way you receive the following benefits:

• You may use the item as a spellcasting focus, and it counts as having a free hand for the purposes of Somatic components
• You gain a +1 magical bonus to attack and damage rolls made with a weapon held in hand, and weapons you wield may utilise your Intelligence modifier for attack and damage rolls instead of Strength or Dexterity
• You gain a +1 magical bonus to spell attack rolls and spell save DC with a spellbook, wand, or other focus held in hand
• You may roll Arcana instead of Acrobatics or Athletics when resisting attempts to Disarm you of a bound item
• While a bound item is within 120ft of you, you may use a Bonus Action to call it into a free hand telekinetically. If the item is held by another creature, you may make a contested Arcana vs Athletics check to rip it from their hands
• You may expend charges to teleport the item to your empty hand instead of calling it telekinetically. It costs 1 charge to teleport the item from within 120ft, 2 charges to summon it from anywhere on the same plane, and 4 charges to summon it from anywhere, even other planes.

  Upgrade - Bind multiple items, gain +1 bonus to attacks/spells while holding a relevant bound item
 

Warrior's Grip

When you take the Attack action, you may expend a charge in order to telekinetically control one of your bound weapons and make an additional attack with it at a range of up to 120ft. You may only use this feature once per Attack action.
  New ability - inspired by Telio and his Swordmaster construct, as well as Sylas' fists
 

Shared Magic

When you or another creature attempts to use a mark granted to it via this item's Arcane Mark feature, it can choose to cast the spell using the power of the gauntlet instead of using their own spell slots. When they do so, they use your Spell DC and Attack Rolls instead of their own, and may benefit from features and modifiers that affect your spellcasting instead of their own. Casting the spell in this way uses a number of charges equal to the spell's level, and may only be done if the caster is on the same plane of existence as you.
  New ability - inspired by Garrac's spell-storing items, and works well with Odessa's "raising others up" concept
 

Unravelling Spellcraft

You may use Arcane Marks to counter the spells of your opponents. When you see a non-epic spell being cast within 60ft, you may use your reaction to expend a mark of the same school as the spell being cast to attempt to cancel it, as if casting Counterspell with a level equal to the level of spell prepared inside the mark.
  New ability - just plain helpful
 

Infusions of Power

If you use both your Arcane Mark and Binding Grip features on the same piece of equipment, you may enchant it for as long as it is both Bound and Marked. You need not be wielding these items to grant it a benefit, and others may gain these benefits if they are wearing or wielding the item instead of you. The exact nature of these enchantments depend on the School of the spell they have been marked with, as listed below:

• Abjuration. Gain a +1 bonus to their AC (may be applied twice to the same creature for a maximum of +2 AC)
• Conjuration. A creature may expend the mark as an action without casting its spell to teleport to a space within 5ft of you, so long as you are on the same plane of existence
• Divination. Gain a +1 bonus to all Saving Throws (may be applied twice to the same creature for a maximum of +2 bonus)
• Enchantment. A creature may expend the mark as a reaction without casting its spell to remove the Charmed or Frightened condition
• Evocation. Gain a +1d4 bonus damage of an element you choose on a hit (may be applied twice to the same creature/weapon for a maximum of 2d4)
• Illusion. A creature may expend the mark as a reaction without casting its spell when they are attacked. When they do so, they interpose a momentary illusory duplicate between themselves and their attacker, making that attack automatically miss
• Necromancy. Gain temporary hit points equal to your Intelligence modifier at the start of the creature's turn. This infusion may not be applied to the same creature multiple times...
• Transmutation. A creature may expend the mark as an action without casting its spell to gain resistance to a damage type of their choice for 1 hour

  New ability - inspired by Garrac's infusions and Sylas' Rune Magic
 

Energetic Reassignment

If you have bound one or more magical items with charges to these gauntlets, you may transfer charges between them. You must be touching the item(s) to do so, and may transfer charges to or from the gauntlets as part of this exchange as well. You may use this property once per day, and regain the ability to do so each dawn.
  New ability - Odessa is a master of altering her own magical energy, this expands it to items
 

Minor Artifact

Though it was neither crafted nor blessed by the Gods, this item is nevertheless an artifact of power. It has 2 Random Minor Beneficial properties, and 1 Minor Detrimental Property.
 

Upgrade Ideas

• More charges!
• Have the Arcane Marks not go away when used to cast spells?
• Multiple extra attacks with Warrior's Grip?
• Major Beneficial property
• Bank charges (temporarily reduce maximum) to ignore the attunement property of 1 or more bound items
• Remove/increase the limit of 2 stacks with various Infusions of Power buffs, and let you stack the necromancy buff
