Notes:
Requires Attunement

This dazzling helm is set with 5 diamonds, 11 rubies, 16 fire opals, and 22 opals. Any gem pried from the helm crumbles to dust. When all the gems are removed or destroyed, the helm loses its magic.

You gain the following benefits while wearing it:

• You can use an action to cast one of the following spells (save DC 18), using one of the helm's gems of the specified type as a component: daylight (opal), fireball (fire opal), prismatic spray (diamond), or wall of fire (ruby). The gem is destroyed when the spell is cast and disappears from the helm.

• As long as it has at least one diamond, the helm emits dim light in a 30-foot radius when at least one undead is within that area. Any undead that starts its turn in that area takes 1d6 radiant damage.

• As long as the helm has at least one ruby, you have resistance to fire damage.

• As long as the helm has at least one fire opal, you can use an action and speak a command word to cause one weapon you are holding to burst into flames. The flames emit bright light in a 10-foot radius and dim light for an additional 10 feet. The flames are harmless to you and the weapon. When you hit with an attack using the blazing weapon, the target takes an extra 1d6 fire damage. The flames last until you use a bonus action to speak the command word again or until you drop or stow the weapon.

Roll a d20 if you are wearing the helm and take fire damage as a result of failing a saving throw against a spell. On a roll of 1, the helm emits beams of light from its remaining gems. Each creature within 60 feet of the helm other than you must succeed on a DC 17 Dexterity saving throw or be struck by a beam, taking radiant damage equal to the number of gems in the helm. The helm and its gems are then destroyed.

flavour This helm is decorated with scenes of underwater volcanoes. While you wear it, you can speak and understand Aquan.

SJ-DC-MONSTER-01 Phoenix
Elemental Essence Shard
Wondrous item, rare (requires attunement by a sorcerer)

This crackling crystal contains the essence of an elemental plane. As an action, you can attach the shard to a Tiny object (such as a weapon or a piece of jewelry) or detach it. It falls off if your attunement to it ends. You can use the shard as a spellcasting focus while you hold or wear it.

Roll a d4 and consult the Elemental Essence Shards table to determine the shard's essence and property. When you use a Metamagic option on a spell while you are holding or wearing the shard, you can use that property.

Elemental Essence Shards

d4 Property
1 Air. You can immediately fly up to 60 feet without provoking opportunity attacks.
2 Earth. You gain resistance to a damage type of your choice until the start of your next turn.
3 Fire. One target of the spell that you can see catches fire. The burning target takes 2d10 fire damage at the start of its next turn, and then the flames go out.
4 Water. You create a wave of water that bursts out from you in a 10-foot radius. Each creature of your choice that you can see in that area takes 2d6 cold damage and must succeed on a Strength saving throw against your spell save DC or be pushed 10 feet away from you and fall prone.
