Magic Items

This javelin is a magic weapon. When you hurl it and speak its command word, it transforms into a bolt of lightning, forming a line 5 feet wide that extends out from you to a target within 120 feet. Each creature in the line excluding you and the target must make a DC 13 Dexterity saving throw, taking 4d6 lightning damage on a failed save, and half as much damage on a successful one. The lightning bolt turns back into a javelin when it reaches the target. Make a ranged weapon attack against the target. On a hit, the target takes damage from the javelin plus 4d6 lightning damage.

The javelin’s property can’t be used again until the next dawn. In the meantime, the javelin can still be used as a magic weapon.

The weaponsmith has in his possession a special +2 mace, made of strange black metal.

A small iron casket among the oni’s belongings holds a gift to the Lord of Oni—a trick box made out of eighteen plates of platinum, eighteen plates of electrum, and eighteen plates of silver. The box is opened by sliding certain plates on the left side, then the top, then the right side in a particular sequence. The correct order is platinum–electrum–silver on each end, and silver–electrum–platinum on the top.
The box has properties similar to those of a bag of holding—although the container is but 10 inches long by 6 inches wide and 4 inches deep, it holds 3 cubic feet of material or 60 pounds, whichever is the lesser
