Runewrought Grenade

Wondrous item, rarity varies

This fist-sized metal ball is engraved with magical runes. As an action, you can activate the grenade’s magic and hurl it at a point on the ground you can see within 60 feet of you. The grenade explodes and produces a specific effect, depending on which type of grenade it is.

• Flashbang (Common). This grenade produces an extremely loud noise and a blinding flash. When the grenade lands, each creature within 20 feet of it must succeed on a DC 15 Constitution saving throw or take 1d8 thunder damage and be blinded and deafened for 1 minute. A creature can repeat this saving throw at the end of each of its turns, ending the effect on itself on a success.
• Gravity (Uncommon). This grenade produces a gravitational blast. When the grenade lands, each creature within 20 feet of it must make a DC 15 Strength saving throw. On a failed save, a creature takes 2d8 force damage and is pulled 10 feet toward the point of impact or pushed 10 feet away from the point of impact (your choice). On a success, a creature takes half as much damage with no additional effects.
• Shrapnel (Uncommon). This grenade explodes in a blast of fire and metal. When the grenade lands, each creature within 20 feet of it must make a DC 15 Dexterity saving throw, taking 4d6 fire damage and 4d6 piercing damage on a failed save, or half as much damage on a successful one.
• Spell (Rare). When you activate this grenade, choose one of the following spells (save DC 15): confusion, fear, hold person, hypnotic pattern, or slow. When the grenade lands, each creature within 20 feet of it is affected as if by that spell (no concentration required).
