Wondrous item, very rare

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.

Weapon (any sword), rare (requires attunement)

When you attack a creature with this magic weapon and roll a 20 on the attack roll, that target takes an extra 3d6 necrotic damage, provided that the target isn’t a construct or an undead. You gain temporary hit points equal to the extra damage dealt.

When you make an Intelligence (Arcana) check to control a sphere of annihilation while you are holding this talisman, you double your proficiency bonus on the check. In addition, when you start your turn with control over a sphere of annihilation, you can use an action to levitate it 10 feet plus a number of additional feet equal to 10 × your Intelligence modifier.

Staff, rare (requires attunement by a bard, cleric, or druid)

This staff has 10 charges. While holding it, 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 spellcasting ability modifier: cure wounds (1 charge per spell level, up to 4th), lesser restoration (2 charges), or mass cure wounds (5 charges).

The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the staff vanishes in a flash of light, lost forever.

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.

Staff, very rare (requires attunement)

This staff can be wielded as a magic quarterstaff that grants a +2 bonus to attack and damage rolls made with it. It also has the following additional properties. When one of these properties is used, it can’t be used again until the next dawn.
Lightning. When you hit with a melee attack using the staff, you can cause the target to take an extra 2d6 lightning damage.
Thunder. When you hit with a melee attack using the staff, you can cause the staff to emit a crack of thunder, audible out to 300 feet. The target you hit must succeed on a DC 17 Constitution saving throw or become stunned until the end of your next turn.
Lightning Strike. You can use an action to cause a bolt of lightning to leap from the staff’s tip in a line that is 5 feet wide and 120 feet long. Each creature in that line must make a DC 17 Dexterity saving throw, taking 9d6 lightning damage on a failed save, or half as much damage on a successful one.
Thunderclap. You can use an action to cause the staff to issue a deafening thunderclap, audible out to 600 feet. Each creature within 60 feet of you (not including you) must make a DC 17 Constitution saving throw. On a failed save, a creature takes 2d6 thunder damage and becomes deafened for 1 minute. On a successful save, a creature takes half damage and isn’t deafened.
Thunder and Lightning. You can use an action to use the Lightning Strike and Thunderclap properties at the same time. Doing so doesn’t expend the daily use of those properties, only the use of this one.

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.
