Magic Items

This staff is made of finely-polished white wood. The insects summoned by the staff take the form of winged spiders with gossamer wings.

Staff, Rare (Requires Attunement by a Bard, Cleric, Druid, Sorcerer, Warlock, or Wizard)
This staff has 10 charges.

Insect Cloud.
While holding the staff, you can take a Magic action and expend 1 charge to cause a swarm of harmless flying insects to fill a 30-foot Emanation originating from you. The insects remain for 10 minutes, making the area Heavily Obscured for creatures other than you. A strong wind (like that created by Gust of Wind) disperses the swarm and ends the effect.

Spells.
While holding the staff, you can cast one of the spells on the following table from it, using your spell save DC and spell attack modifier. The table indicates how many charges you must expend to cast the spell.
Spell Charge Cost
Giant Insect 4
Insect Plague 5

Regaining Charges.
The staff regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll 1d20. On a 1, a swarm of insects consumes and destroys the staff, then disperses.

Wondrous item, rare (requires attunement)
While wearing this cloak, you can use an action to speak its command word. This turns the cloak into a pair of bat wings or bird wings on your back for 1 hour or until you repeat the command word as an action. The wings give you a flying speed of 60 feet. When they disappear, you can't use them again for 1d12 hours.

Weapon (Longbow), Rare (Requires Attunement)

The limb tips of this magic bow are shaped like a dragon’s wings, and the weapon is infused with the essence of an amethyst dragon’s breath. When you hit with an attack roll using this magic bow, the target takes an extra 1d6 force damage.
If you load no ammunition in the weapon, it produces its own, automatically creating one piece of magic ammunition when you pull back the string. The ammunition created by the bow vanishes the instant after it hits or misses a target.

Range. A Range weapon has a range in parentheses after the Ammunition or Thrown property. The range lists two numbers. The first is the weapon's normal range in feet, and the second is the weapon's long range. When attacking a target beyond normal range, you have Disadvantage on the attack roll. You can't attack a target beyond the long range.

Ammunition. You can use a weapon that has the Ammunition property to make a ranged attack only if you have ammunition to fire from it. The type of ammunition required is specified with the weapon's range. Each attack expends one piece of ammunition. Drawing the ammunition is part of the attack (you need a free hand to load a one-handed weapon). After a fight, you can spend 1 minute to recover half the ammunition (round down) you used in the fight; the rest is lost.

Heavy. You have Disadvantage on attack rolls with a Heavy weapon if it's a Melee weapon and your Strength score isn't at least 13 or if it's a Ranged weapon and your Dexterity score isn't at least 13.

Two-Handed. A Two-Handed weapon requires two hands when you attack with it.

Mastery: Slow. If you hit a creature with this weapon and deal damage to it, you can reduce its Speed by 10 feet until the start of your next turn. If the creature is hit more than once by weapons that have this property, the Speed reduction doesn't exceed 10 feet.
