Magic Items

Armor (shield), uncommon - 6 lb. AC +2
While holding this shield, you have advantage on initiative rolls and Wisdom (Perception) checks. The shield is adorned with a big eye propped against it.

Staff, rare (requires attunement by a Druid)
This staff can be wielded as a magic quarterstaff that grants a +2 bonus to attack and damage rolls made with it. While holding it, you have a +2 bonus to spell attack rolls.
The staff has 10 charges for the following properties. It regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff loses its properties and becomes a nonmagical quarterstaff.
Spell. You can use an action to expend 1 or more of the staff's charges to cast one of the following spells from it, using your spell save DC:

Animal Friendship (1 charge)
Awaken (5 charges)
Barkskin (2 charges)
Locate Animals or Plants (2 charges)
Speak with Animals (1 charge)
Speak with Plants (3 charges)
Wall of Thorns (6 charges).

You can also use an action to cast the pass without trace spell from the staff without using any charges.

Tree Form. You can use an action to plant one end of the staff in fertile earth and expend 1 charge to transform the staff into a healthy tree. The tree is 60 feet tall and has a 5-foot-diameter trunk, and its branches at the top spread out in a 20-foot radius. The tree appears ordinary but radiates a faint aura of transmutation magic if targeted by detect magic. While touching the tree and using another action to speak its command word, you return the staff to its normal form. Any creature in the tree falls when it reverts to a staff.

Wondrous Item, rare (requires attunement by a Cleric, Druid, or Paladin)
This necklace has 1d4 + 2 magic beads made from aquamarine, black pearl, or topaz. It also has many nonmagical beads made from stones such as amber, bloodstone, citrine, coral, jade, pearl, or quartz. If a magic bead is removed from the necklace, that bead loses its magic.
Six types of magic beads exist. The GM decides the type of each bead on the necklace or determines it randomly. A necklace can have more than one bead of the same type. To use one, you must be wearing the necklace. Each bead contains a spell that you can cast from it as a bonus action (using your spell save DC if a save is necessary). Once a magic bead's spell is cast, that bead can't be used again until the next dawn.

Wondrous item (tattoo), rarity varies (requires attunement)
Tattoo Attunement. To attune to this item, you hold the needle to your skin where you want the tattoo to appear, pressing the needle there throughout the attunement process. When the attunement is complete, the needle turns into the ink that becomes the tattoo, which appears on the skin.
If your attunement to the tattoo ends, the tattoo vanishes, and the needle reappears in your space.
Protection. While you aren't wearing armor, the tattoo grants you an Armor Class depending on the tattoo's rarity, as shown below. You can use a shield and still gain this benefit.
Rarity - AC
Very Rare - 18

Wondrous item, legendary (requires attunement)
This scarf is made of sturdy cloth and covered in platinum-colored scales.
As an action, you can pull a scale from the scarf and speak a command word. When you do so, choose one of the following effects:
Breath of Life. The scale disappears, and you or a creature you touch regains 10d4 hit points.
Platinum Shield. For 1 hour or until you dismiss it (no action required), the scale becomes a +1 shield, which you or another creature can use. A creature wielding the shield has immunity to radiant damage.
Radiant Hammer. For 1 hour or until you dismiss it (no action required), the scale becomes a magic light hammer, which you or another creature can use. The weapon deals 2d4 radiant damage, instead of the bludgeoning damage normal for a light hammer. It deals an extra 2d4 radiant damage to chromatic dragons.
Once three scales have been pulled from the scarf, no more scales can be removed until the next dawn, when all the missing scales grow back. If you pull off a scale but don't speak a command word, it disappears after 1 minute.
This black scarf is made out of silk with interwoven leafs that can be plucked from it, these magic leafs seem to grow back after a day or so.

You gain one 9th-level spell slot, provided that you already have one.
Imbued with the power of the Multiversal Championship, you gain an additional 9th-level spell slot, provided that you already have one. This epic boon, granted only to the greatest champions, enhances your magical prowess, allowing you to cast the most potent spells with unparalleled mastery.
Note: In T4 only you can replace all consumables with a boon; while a boon can be given to a character that is not yet 20th level it does not take effect until they reach that level. You need to include this information in the adventure.

Staff, legendary (requires attunement by a sorcerer, warlock, or wizard)
This staff can be wielded as a magic quarterstaff that grants a +2 bonus to attack and damage rolls made with it. While you hold it, you gain a +2 bonus to spell attack rolls.
The staff has 50 charges for the following properties. It regains 4d6 + 2 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 20, the staff regains 1d12 + 1 charges.
Spell Absorption. While holding the staff, you have advantage on saving throws against spells. In addition, you can use your reaction when another creature casts a spell that targets only you. If you do, the staff absorbs the magic of the spell, canceling its effect and gaining a number of charges equal to the absorbed spell’s level. However, if doing so brings the staff’s total number of charges above 50, the staff explodes as if you activated its retributive strike (see below).
Spells. While holding the staff, you can use an action to expend some of its charges to cast one of the following spells from it, using your spell save DC and spellcasting ability: conjure elemental (7 charges), dispel magic (3 charges), fireball (7th-level version, 7 charges), flaming sphere (2 charges), ice storm (4 charges), invisibility (2 charges), knock (2 charges), lightning bolt (7th-level version, 7 charges), passwall (5 charges), plane shift (7 charges), telekinesis (5 charges), wall of fire (4 charges), or web (2 charges).
You can also use an action to cast one of the following spells from the staff without using any charges: arcane lock, detect magic, enlarge/reduce, light, mage hand, or protection from evil and good.
Retributive Strike. You can use an action to break the staff over your knee or against a solid surface, performing a retributive strike. The staff is destroyed and releases its remaining magic in an explosion that expands to fill a 30-foot-radius sphere centered on it.
You have a 50 percent chance to instantly travel to a random plane of existence, avoiding the explosion. If you fail to avoid the effect, you take force damage equal to 16 × the number of charges in the staff. Every other creature in the area must make a DC 17 Dexterity saving throw. On a failed save, a creature takes an amount of damage based on how far away it is from the point of origin, as shown in the following table. On a successful save, a creature takes half as much damage.
