Magic Items

Wondrous Item, varies (requires attunement)
An Ioun stone is named after Ioun, a god of knowledge and prophecy revered on some worlds. Many types of Ioun stone exist, each type a distinct combination of shape and color.

When you use an action to toss one of these stones into the air, the stone orbits your head at a distance of 1d3 feet and confers a benefit to you. Thereafter, another creature must use an action to grasp or net the stone to separate it from you, either by making a successful attack roll against AC 24 or a successful DC 24 Dexterity (Acrobatics) check. You can use an action to seize and stow the stone, ending its effect.

A stone has AC 24, 10 hit points, and resistance to all damage. It is considered to be an object that is being worn while it orbits your head.

Mastery (Legendary). Your proficiency bonus increases by 1 while this pale green prism orbits your head.

Rod, legendary (requires attunement by a cleric, druid, or paladin)
The rod has 5 charges. While you hold it, you can use an action to cast one of the following spells from it: heal (expends 1 charge) or resurrection (expends 5 charges).

The rod regains 1 expended charge daily at dawn. If the rod is reduced to 0 charges, roll a d20. On a 1, the rod disapears in a burst of radiance.

Potion, legendary
When you drink this potion, you become Huge for 24 hours if you are Medium or smaller, otherwise the potion does nothing. For that duration, your Strength becomes 25, if it isn’t already higher, and your hit point maximum is doubled (your current hit points are doubled when you drink the potion). In addition, the reach of your melee attacks increases by 5 feet.

Everything you are carrying and wearing also increases in size for the duration. When rolling damage for weapons enlarged in this manner, roll three times the normal number of dice; for example, an enlarged longsword would deal 3d8 slashing damage (instead of 1d8), or 3d10 slashing damage (instead of 1d10) when used with two hands.

When the effect ends, any hit points you have above your hit point maximum become temporary hit points.

This potion is a pale white liquid made from the tongue of a giant clam, with a pungent aroma akin to that of rotting algae. It tastes sweet, however, when consumed.

Notes: Buff, Shapechanging

ASCENDANT GEM DRAGON-TOUCHED FOCUS
Wondrous Item, Legendary (Requires Attunement by a
Spellcaster)
This wondrous item can be a scepter, an orb, an amulet, a crystal, or another finely crafted object. It typically incorporates imagery of dragons’ wings, claws, teeth, or scales. While carrying it, you gain the following benefits:
 You have advantage on initiative rolls. While you are holding the focus, it can function as a spellcasting focus for all your spells.
 Whenever you use a spell slot to cast a spell, you can immediately teleport to an unoccupied space you can
see within 15 feet of you.
 While you are holding the focus, you can use it to cast the following spells: Rary’s telepathic bond, Raulothim’s psychic lance. Once the item is used to cast a given spell, it can’t be used to cast that spell again until the next dawn.
 When you cast a spell of 1st level or higher while holding this focus, you can treat the spell as if it were
cast using a 9th-level spell slot. Once this property is used, it can’t be used again until the next dawn.
Due to the strange magic that trapped Amaranthraxine’s spirit in the walls of Xorvintroth, this hoard item can’t increase or decrease in power.

Armor (chain mail), legendary (requires attunement)
While wearing this armor, you gain a +3 bonus to AC, you are immune to fire damage, and you can understand and speak Primordial. In addition, you can stand on and walk across molten rock as if it were solid ground.
This item can be found in the Dungeon Master’s Guide. See Player Handout 3 for more details.

Weapon (scimitar), legendary (requires attunement)

This blade hums and vibrates with great energy, and slices through obstacles with the greatest of ease. If the sword does not claim the life of a sentient creature each day, you find that you are easily angered and become frustrated by even the smallest obstacles.

Weapon (any sword that deals slashing damage), legendary (requires attunement)
You gain a +3 bonus to attack and damage rolls made with this magic weapon. In addition, the weapon ignores resistance to slashing damage.

When you attack a creature that has at least one head with this weapon and roll a 20 on the attack roll, you cut off one of the creature's heads. The creature dies if it can't survive without the lost head. A creature is immune to this effect if it is immune to slashing damage, doesn't have or need a head, has legendary actions, or the GM decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead takes an extra 6d8 slashing damage from the hit.

You imbue a creature you touch with positive energy to undo a debilitating effect. You can reduce the target's exhaustion level by one, or end one of the following effects on the target:

One effect that charmed or petrified the target
One curse, including the target's attunement to a cursed magic item
Any reduction to one of the target's ability scores
One effect reducing the target's hit point maximum
* - (diamond dust worth at least 100 gp, which the spell consumes)

Potion, very rare
When you drink this potion, it removes any exhaustion you are suffering and cures any disease or poison affecting you. For the next 24 hours, you regain the maximum number of hit points for any Hit Die you spend. The potion's crimson liquid regularly pulses with dull light, calling to mind a heartbeat.

Notes: Cures Disease, Removes Poison, Max HP from Hit Dice, Healing, Consumable

Potion, Very Rare
When you drink this potion, you gain the effect of the haste
spell for 1 minute (no concentration required). The potion’s
yellow fluid is streaked with black and swirls on its own.

Player Name: Matt Lincicum. Character Name: Brocc. Location: Tomb of Horrors. Item: Staff of Power. Very Rare.

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 gain a +2 bonus to Armor Class, saving throws, and spell attack rolls.

The staff has 20 charges for the following properties. The staff regains 2d8 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff retains its +2 bonus to attack and damage rolls but loses all other properties. On a 20, the staff regains 1d8 + 2 charges.

Power Strike. When you hit with a melee attack using the staff, you can expend 1 charge to deal an extra 1d6 force damage to the target.

Spells. While holding this staff, you can use an action to expend 1 or more of its charges to cast one of the following spells from it, using your spell save DC and spell attack bonus: cone of cold (5 charges), fireball (5th-level version, 5 charges), globe of invulnerability (6 charges), hold monster (5 charges), levitate (2 charges), lightning bolt (5th-level version, 5 charges), magic missile (1 charge), ray of enfeeblement (1 charge), or wall of force (5 charges).

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.

Item: Belt of Fire Giant Strength
Character: Amrath
Player: Blazicken DCI: 1319047975
Adventure: DDHC-TYP Tales from the Yawning Portal - Tomb of Horrors

Wondrous Item, very rare (requires attunement)
While wearing this belt, your Strength score changes to 25. The item has no effect on you if your Strength without the belt is equal to or greater than 25.

Notes: Set: Strength Score, Buff, Belt

Potion, varies
When you drink a potion of mind control, you can cast a dominate spell (save DC 15) on a specific creature if you do so before the end of your next turn. If you don’t, the potion is wasted.

A potion of mind control produces the effect of a dominate beast, a dominate person (humanoid), or a dominate monster spell (see the table below). If the target’s initial saving throw fails, the effect lasts for 1 hour, with no concentration required on your part. The charmed creature has disadvantage on new saving throws to break the effect during this time.

This book contains memory and logic exercises, and its words are charged with magic. If you spend 48 hours over a period of 6 days or fewer studying the book's contents and practicing its guidelines, your Intelligence score increases by 2, as does your maximum for that score. The manual then loses its magic, but regains it in a century.
