Horseshoes of speed (R)

Rare

These iron horseshoes come in a set of four. While all four shoes are affixed to the hooves of a horse or similar creature, they increase the creature's walking speed by 30 feet.

Necklace of Fireball (R)

Rare

This necklace has 1d6 + 3 (6) beads hanging from it. You can use an action to detach a bead and throw it up to 60 feet away. When it reaches the end of its trajectory, the bead detonates as a 3rd-level Fireball spell (save DC 15). You can hurl multiple beads, or even the whole necklace, as one action. When you do so, increase the level of the Fireball by 1 for each bead beyond the first.
