Here’s a few more homebrewed magic items that have appeared in my campaign recently. The Warclub of Death is based on one of my son’s ideas. He’s awesome!

Dryad’s Evolving Bow

Weapon (Longbow), Very Rare (requires attunement)

Offered by a grateful dryad, this longbow starts as a +1 magic weapon but evolves over time. Each 3 levels you have had the dryad’s evolving bow attuned you can strengthen the bow as follows (in order):

• Add +1d4 piercing damage (thorns appear on arrows as they hit a target)
• The dryad’s evolving bow is now +2
• If an arrow hits something, you can then cast Grasping Vine as a bonus action, with the arrow as the targeted spot of the spell.  The bow has 3 charges, it regains 1d2+1 charges each dawn
• The dryad’s evolving bow is now +3
• You can cast Tree Stride as a bonus action, it costs 2 charges to do so, the bow has now 7 charges, it regains 1d6+1 charges each dawn

Curse

Curse of the Tree Hugger. While you are attuned to this bow, you have disadvantage to any attacks you make against plant-type creatures.

Cloak of the Dragonfly

wondrous item, rare (requires attunement)

While flying, your speed is increased by 10′. Additionally, Stirges are very reluctant to attack you and won’t do so unless absolutely cornered.

Boots of Bug Squashing

wondrous item, rare (requires attunement)

As a bonus action, you can make a (strength) melee attack against an insect-type creature (or swarm) for 2d6 + str damage.

Poniard of the Ancient One

weapon (dagger), rare

This + 1 dagger has 3 charges. When you hit with an attack, as a free action, you can expand a charge to paralyze the target for 1 round (constitution save DC 12). The poniard regains all of its charges after a long rest.

Warclub of Death (probably yours)

weapon (club), very rare (requires attunement)

This is as a Nine Lives Stealer +2 club.

Curse, Atavistic Instinct: While attuned to the Warclub of Death, you can’t stand the idea of wearing any clothing or armor.

Lord Snail’s Magic Shell

Wondrous item, very rare

This large shell functions as a Bag of Holding.

Curse: Legacy of a Pervert

Whenever you try to retrieve an item (as an action) from the Lord Snail’ Shell, you have 50% chance to pick instead one of the late Lord Snail’s innumerable erotic charcoal drawings (depicting his ertswhile dungeon neighbour, a beautiful Nereid).

Hat of the Spider

Wondrous item, rare (requires attunement)

While wearing this hat, you gain the following benefits:

• You ignore movement restrictions caused by webbing.
• You have the ability to comprehend and verbally communicate with spiders.
• You can use an action to conjure a Swarm of Spiders (Monster manual: Swarm of Insects statistics) within 90′ of you that will be under your control for 10 minutes and then disappears. Once used, this property of the hat can’t be used again until next dawn.

Broadsword of the Philistine

weapon (sword), rare (requires attunement)

This is a +1 longsword. If both your intelligence and wisdom bonuses (taken separately) are lower than your target’s, you add 1d8 to damage.

Curse of the Philistine: While attuned to this weapon you lose one non-weapon proficiency (determined randomly each day).
