Magic Items

Eternal Bond (Blast Scepter with Harmonious property)
Rod, very rare (requires attunement)

Whoever is attuned to the Blast Scepter gains resistance to fire and lightning damage and can, as an action, use it to cast thunderwave as a 4th-level spell (save DC16) without expending a spell slot.

Flavor: This scepter is forged from a rare, ethereal wood that seems to shimmer with an ever-changing array of hues, reminiscent of the vibrant colors found in Feywild. The wood is adorned with delicate, silver filigree that twists and spirals around the scepter, creating the looks of vines and leaves dancing in unseen breezes. A careful look spots the word 'From Echthra, to Charlie' carved onto it.

Weapon (shortsword), very rare (requires attunement)

When you hit with an attack using this magic sword, the target takes an extra 1d6 cold damage. In addition, while you hold the sword, you have resistance to fire damage.

When you draw this weapon, you can extinguish all nonmagical flames within 30 feet of you. This property can be used no more than once per hour.

Proficiency with a shortsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Weapon (spear), very rare (requires attunement by a elf)

The nereid wears a mantle of silky cloth the color of sea foam, which holds the creature's spirit. The mantle has an AC and hit points equal to that of the nereid, but the garment can't be directly harmed while the nereid wears it. If the mantle is destroyed, the nereid becomes poisoned and dies within 1 hour. A nereid is willing to do anything in its power to recover the mantle if it is stolen, including serving the thief.
