Band of Explosive Cantrips

This silver band is intricately carved with magical sigils. Whenever you cast a cantrip where you make a spell attack and roll a critical hit, the spell also affects all creatures within 5 feet of the original target.

Catastrophic Cantrip Collection. There are six items in this collection. Each piece grants your cantrips additional firepower. Additionally, attuning to any number of the Catastrophic Cantrip Collection only uses one of your attunement slots.

• 1 Piece. You gain a +1 bonus to your spell attack rolls and save DCs when casting cantrips.
• 2 Pieces. Your cantrips that don't have a range of self or touch have their range increased by 10 feet per attuned piece.
• 3 Pieces. When you cast a cantrip that has a casting time of 1 action, you can instead change the casting time to 1 bonus action. You can use this feature a number of times equal to the number of pieces you are attuned to. You regain all expended uses after a long rest.
• 4 Pieces. Add one cantrip from any spell list to your spell list. You lose this cantrip if you are no longer attuned to at least 4 pieces.
• 5 Pieces. Each morning select a damage type from any cantrip you know. You have resistance to this damage type until the following morning. You cannot select the same damage type twice in a row.
• 6 Pieces -Catastrophe. When you are attuned to all six pieces of the Catastrophic Cantrip Collection you gain access to this feature. Your cantrips rend through foes like no other in the land. All of your cantrips that require spell attacks gain the following improvements:
  • Unwavering Aim If you roll a 1 or 2 on your attack roll, you may choose to reroll it. You must use the new roll.
  • Powerful Magics When you roll a 1 or 2 on a damage die, you can reroll the die, and must use the new roll, even if the new roll is a 1 or 2.
  • Irresistible Damage Creatures cannot resist damage from you cantrips. This has no effect on immunity.
  • Cataclysmic Power Whenever a damage die rolls its maximum value, roll it again and add the new roll to the total. If this roll is the maximum value, do this again. Continue to do this until no damage dice roll maximum value. If seven or more dice are rerolled, the power surging through you becomes too much, and you take damage equal to the total rolled. This damage cannot be resisted or ignored in any way.
