Wondrous Item, uncommon

While you wear these boots, your steps make no sound, regardless of the surface you are moving across. You also have advantage on Dexterity (Stealth) checks that rely on moving silently.
Unworn, these eladrin-crafted boots appear to be little more than crude tubes of birch bark sewn roughly together with sinew.
Worn, they transform into slippers that match the seasons.
Elk-hide in winter, kelp-wrapped for the wet spring, straw sandals for summer and soft down-lined shoes for fall.

This book is covered in fine leather, with a symbol of a harp embossed onto the spine. On the inside cover is the inscription: “Thanks for getting the books for me. Hopefully we meet again. —O. E.”.

Wondrous item, minor tier, common (requires attunement by a spellcaster)

Etched with eldritch runes, this 1-inch-diameter ruby allows you to use a simple or martial weapon as a spellcasting focus for your spells. For this property to work, you must attach the ruby to the weapon by pressing the ruby against it for at least 10 minutes. Thereafter, the ruby can't be removed unless you detach it as an action or the weapon is destroyed. Not even an antimagic field causes it to fall off. The ruby does fall off the weapon if your attunement to the ruby ends.

Weapon (any sword), common

In darkness, the unsheathed blade of this sword sheds moonlight, creating bright light in a 15-foot radius and dim light for an additional 15 feet.
The blade is thin to the point of being paper.
Geometric runes run along its length, in stark contrast to the sweeping elven make.
The script is unknown, but purportedly (or with the help of comprehend languages) it reads:
“I am but a shard. Find Xintocan.”

While you are playing this musical instrument, you can create harmless, illusionary visual effects within a 5-foot-radius sphere centered on the instrument. If you are a bard, the radius increases to 15 feet. Sample visual effects include luminous musical notes, a spectral dancer, butterflies, and gently falling snow. The magical effects have neither substance nor sound, and they are obviously illusory. The effect ends when you stop playing. This item can be found in Xanathar’s Guide to Everything.

Wondrous Item, common

This horn has 4 charges. When you use an action to blow it, one creature of your choice can hear the horn’s blare, provided the creature is within 600 feet of the horn and not deafened. No other creature hears sound coming from the horn. The horn regains 1d4 expended charges daily at dawn.

The otherworldly tone of this horn sounds like the reverberation of clear crystals.

The user and recipient of the horn’s signal feel a warm, calming sensation spreading across their bodies, which dissipates after one round.
