Singing Moss Focus

Wondrous Item (arcane focus), uncommon (requires attunement by a druid or shaman)

This focus is a small, hand-held container made of polished sea-glass, containing a vibrant patch of "Singing Moss" from The Echoing Grotto. The moss vibrates gently, producing a low, soothing hum that resonates with the user's heartbeat.

Properties

While using this focus to cast spells, you gain the following benefits:

1. Nature’s Voice: You can cast the Speak with Plants spell once per day without expending a spell slot.

2. Echoing Spell: When you cast a spell that deals thunder or cold damage, you can choose to have the spell's sound echo. All creatures within 10 feet of the target must succeed on a DC 12 Constitution save or be Deafened for 1 round.

3. Mist-Communion: While within The Shrouded Boughs, you can use the focus to cast Augury as a ritual, with the forest's spirits providing the answers.

4. Resonance: If you take thunder damage while holding the focus, you take 1d4 additional thunder damage as the moss vibrates violently.
