I even gave the PC's a magic item that grants Inspiration. It's a mirror with the words "I'm good enough, I'm smart enough, and gosh-darn it people like me" written on it in 4 languages (elvish, dwarvish, orcish, and common). Read the inscription and you get Inspired (1 use per day)!
Awesome! I have a ton of magic items that interact with the inspiration rules (and the bardic inspiration rules). For instance:
Flute of Perfect Inspiration
Wondrous item, very rare (requires attunement by a proficient creature)
If a creature that you can see within 30' other than yourself spends a bardic inspiration die while you hold this flute, you can use your reaction to play a tune to inspire it yet further. The creature rolls two inspiration dice and takes the better one.
In addition, if a creature that you can see within 30' other than yourself rolls with advantage because it uses its inspiration, you can use your reaction to play a tune to inspire it yet further. The creature rolls 3d20s instead of two and chooses the one it prefers.
Inspirational Elixir
Potion, uncommon
When you drink this potion, if you are a bard, you regain one spent bardic inspiration die.
Medallion of Inspiration
Wondrous item, uncommon
Whenever you use your inspiration to make a roll with advantage, you also gain 5 temporary hit points.
Ring of Rhyming
Ring, common
This ring compels you to speak in rhyme. If you speak without rhyming, you lose inspiration and can't get it (including from another pc) until you complete a long rest.
Once this ring is on your finger, it clings tenaciously to you and can't be removed without a remove curse spell.
Wand of Inspired Alacrity
Wand, common (requires attunement by a spellcaster)
While you use this wand as a spellcasting focus, you can expend your inspiration to cast a spell that normally has a casting time of 1 action with a bonus action instead.
