Cataclysm Bolt

Catalysm Bolts are magical, dwarven-made, crossbow ammunition that have a random unpredictable additional area effect damage bonus. These crossbow bolts were first created during the Scattered War by the Jaggenstrike Clan founders of the Kraghammer.

Description
The bolts act as normal crossbow bolts, but on impact, the user rolls a d6 to determine the kind of additional damage that may occur. On a roll of 1-2, the bolt explodes, dealing fire damage to the creatures within 5 feet of it; on 3-4, the bolt freezes and damages nearby creatures, with the chance to restrain them.; on 5, the target takes necrotic damage and can be stunned until the end of their next turn; on 6, the bolt splits in 7 parts, unleashing a burst of shrapnel.

Once the bolt hits, the enchantment ends and it becomes a normal piece of ammunition.

History
The Mighty Nein found three Cataclysm Bolts inside a case in Vokodo's lair, and Veth took them. She used the first one against Gelidon in Eiselcross, but the additional damage roll was for cold, which Gelidon was immune to. The remaining two were used against the fire guardian on the Elemental Plane of Fire, and both additional damage rolls were for fire, which the guardian was immune to.

Trivia
All three times Veth used the Cataclysm Bolts, the target was immune to the extra damage from the bolts.
