Magic Items

Weapon (arrow), very rare
An arrow of slaying is a magic weapon meant to slay a particular kind of creature. Some are more focused than others; for example, there are both arrows of dragon slaying and arrows of blue dragon slaying. If a creature belonging to the type, race, or group associated with an arrow of slaying takes damage from the arrow, the creature must make a DC 17 Constitution saving throw, taking an extra 6d10 piercing damage on a failed save, or half as much extra damage on a successful one.

Once an arrow of slaying deals its extra damage to a creature, it becomes a nonmagical arrow.

Other types of magic ammunition of this kind exist, such as bolts of slaying meant for a crossbow, though arrows are most common.

Potion, legendary
This potion looks like liquid gold, with a single scale from a chromatic, gem, or metallic dragon suspended in it. When you drink this potion, you transform into an adult dragon of the same kind as the dragon the scale came from. The transformation lasts for 1 hour. Any equipment you are wearing or carrying melds into your new form or falls to the ground (your choice). For the duration, you use the game statistics of the adult dragon instead of your own, but you retain your languages, personality, and memories. You can’t use a dragon's Change Shape or its legendary or lair actions.

Wondrous item, rare (requires attunement)

This pearl-studded amulet is also a magical compass. The wielder can use an action to learn which way is north. Your Constitution score is 19 while you wear this amulet. It has no effect on you if your Constitution is 19 or higher without it.

Weapon (crossbow bolt), uncommon
These four crossbow bolts are inscribed with the Dethek rune “alagh,” meaning “valor.” You have a +1 bonus to attack and damage rolls made with this piece of magic ammunition. Once it hits a target, the ammunition is no longer magical.

Armor (studded leather), uncommon
Made from tough, flexible shark leather, this armor is reinforced with close-set coral spikes.
While wearing this armor, you have a swimming speed equal to your walking speed. In addition, whenever you
start your turn underwater with 0 hit points, the armor causes you to rise 60 feet toward the surface. The armor is decorated with fish and shell motifs.

Potion, rare
For 1 hour after drinking this potion, you gain 10 temporary hit points that last for 1 hour. For the same
duration, you are under the effect of the bless spell (no concentration required). This blue potion bubbles and
steams as if boiling.

Potion, rare
When you drink this potion, it cures any disease afflicting you, and it removes the blinded, deafened, paralyzed, and poisoned conditions. The clear red liquid has tiny bubbles of light in it.
