The idea for this item was due to someone close to me bombing on stage (in game, not IRL) and wanting to run away real quick, so I figured some speedy pants might help if such a scenario arose again.
The tiny piano is for all the times my friends IRL pulled out their guitar which is easy to carry, to impress us, and I was just standing there like "Well just you wait until I pull out my grand piano, my time will come". My time never came...
Anyway! On Patreon, I delve into even more bard options for the game if you're interested in that (alongside over 600 pages of D&D options for your games)
wonderous item (pants), rare (requires attunement by a Bard)
These fabric pants have a patchwork design made of countless colored squares. For some reason, even when no one is wearing them, they seem to tumble and move on their own.
While wearing these pants, you gain the following features:
Your movement speed is increased by 10 feet.
You gain proficiency in the Dexterity (Acrobatics) skill. If you already had proficiency in the skill, your proficiency bonus is doubled on all checks you make with that skill.
Whenever you use your Bardic Inspiration, your movement speed is increased by another 5 feet until the end of your turn.
wonderous item, uncommon
This toy piano is small enough to fit within even the smallest of pockets. When thrown on the ground, instead of breaking, it grows in size to become a large piano, which you can play normally. If you tap it on the hood two times, it shrinks back down.
