Does Arcane Focus Only Affect Arcane Spells?

The Arcane Focus is a special item designed to channel the power of arcane spells, and its primary function is to replace the need for material components in spellcasting, but it does indeed only affect arcane spells. The hit bonus from an Arcane Focus is specifically tailored for arcane spells, such as sheep or counterspell, providing a 6% base chance to hit, similar to how elemental precision works for frost and fire spells.

Understanding Arcane Focus

What is an Arcane Focus?

An Arcane Focus can be used in place of a spell component pouch for the purpose of a spell’s inexpensive material components, essentially granting the user the Eschew Materials feat while using the focus to cast a spell.
