Infernal Weapon
When you cast the spell, choose either a flame fork or ice spear. While the spell lasts, you can use an action to make a melee spell attack with the weapon against a creature within 10 feet of you.
On a hit, you deal 5d8 damage of a type determined by the weapon's form. On a critical hit, you inflict an additional effect.
In addition, on a hit with the infernal weapon, you can end the spell early to inflict an automatic critical hit.
**Flame Fork.** The weapon deals fire damage.
On a critical hit, the target catches fire, taking 2d6 ongoing fire damage.
**Ice Spear.** The weapon deals cold damage. On a critical hit, for 1 minute the target is slowed.
At the end of each of its turns a slowed creature can make a Constitution saving throw, ending the effect on itself on a success.
A creature reduced to 0 hit points by an infernal weapon immediately dies in a gruesome fashion.
For example, a creature killed by an ice spear might freeze solid, then shatter into a thousand pieces. Each creature of your choice within 60 feet of the creature and who can see it when it dies must make a Wisdom saving throw. On a failure, a creature becomes frightened of you until the end of your next turn.
