Magic Items

3 Arrow of Dragon Slaying,

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.

Weapon (dagger), rare

A dagger fashioned from the tooth of a dragon. While the blade is obviously a fang or predator’s tooth, the handle is leather wrapped around the root of the tooth, and there is no cross-guard.

You gain a +1 bonus to attack rolls and damage rolls you make with this weapon. On a hit with this weapon, the target takes an extra 1d6 acid damage.

Draconic Potency. Against enemies of the Cult of the Dragon, the dagger’s bonus to attack rolls and damage rolls increases to +2, and the extra acid damage increases to 2d6.

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

Elemental Gem Blue (Air)
Wondrous item, uncommon

This gem contains a mote of elemental energy. When you use an action to break the gem, an elemental is summoned as if you had cast the conjure elemental spell, and the gem's magic is lost. The type of gem determines the elemental summoned by the spell.
