From publisher blurb:
For too long, Spellcasting Focuses have been relegated to a footnote on character sheets. The iconic implements of magic users have done nothing to set one character apart from another. Sure, magic staffs and wands give a caster more spells but are no different in the hands of a master or an initiate. Enhanced Focuses increase a spell caster’s magical powers, in the same way a flaming longsword does for the fighter.
This 18-page supplement provides 71 arcane focuses, druid focuses, holy symbols, and bardic instruments to boost your casting prowess. Plus 5 pages for DMs on using Enhanced Focuses as plot hooks, investing your players in their characters’ and the campaign’s story.
