Imbued Wood Focus

From Eberron: Rising From the Last War, page 277; and Wayfinder's Guide to Eberron, page 114.

Description
Wondrous item, common (requires attunement).

An imbued wood focus is a rod, staff, or wand cut from a tree infused with extra-planar energy. If you're a spellcaster, you can use this orb as a spellcasting focus.

When you cast a damage-dealing spell using this item as your spellcasting focus, you gain a +1 bonus to one damage roll of the spell, provided the damage is of the type associated with the item's wood. The types of wood and their associated damage types are listed in the Imbued Wood Focus table.

Powerful manifest zones can infuse local trees with planar energies. A gifted artificer can tap into this to create a wand, staff, or rod that is especially effective at channeling a particular type of energy.

When you cast a spell that deals damage of the type associated with the material your arcane focus is made from, the spell gains a +1 bonus to one damage roll of that spell. The materials and their associated damage types are listed here.
