Magic Items

Amarantha’s Heart (Dark Shard Amulet)
Wondrous Item, common (requires attunement by a warlock)

While you are wearing it, you gain the following benefits:

• You can use the amulet as a spellcasting focus for your warlock spells

• You can try to cast a cantrip you don’t know. The cantrip must be on the warlock spell list, and you must make a DC 10 Intelligence (Arcana) check. If the check succeeds, you cast the spell. If the check fails, so does the spell, and the action used to cast the spell is wasted. In either case, you can’t use this property again until you finish a long rest.

This amulet is shaped like a stylized heart – the heart seems to absorb all light into it, and is always pitch dark. When in dim light, the heart seems to have mists swirling around in it. The amulet is supported by a thin gold chain.

This item can be found in the Xanathar’s Guide to Everything.

+1 All-Purpose Tool

Wondrous item, uncommon (requires attunement by an artificer)

This simple screwdriver can transform into a variety of tools; as an action, you can touch the item and transform it into any type of artisan's tool of your choice (see the "Equipment" chapter in the Player's Handbook for a list of artisan's tools). Whatever form the tool takes, you are proficient with it.

While holding this tool, you gain a +1 bonus to the spell attack rolls and the saving throw DCs of your artificer spells.

As an action, you can focus on the tool to channel your creative forces. Choose a cantrip that you don't know from any class list. For 8 hours, you can cast that cantrip, and it counts as an artificer cantrip for you. Once this property is used, it can't be used again until the next dawn.

Additional Minor Property:

Since this tool has been carved out of the Treant Key Duot'ho's own wood, it is infused with a glimpse of his power (his voice):

War Leader. The bearer can use an action to cause his or her voice to carry clearly for up to 300 feet until the end of the bearer's next turn.
