Bard: College Of Entropy

Bards of the College of Entropy are itinerate gamblers
and daring thrill seekers whose actions are supremely
unpredictable. Rather than relying on ancient lore or
skill with arms, these bards throw themselves into new
challenges just to see what happens, trusting in luck to see
them through. They're called luck stealers (with a mixture
of derision and respect), because no matter how bad things
get for everyone around them, these bards always seem to
come out unscathed.

Bonus Proficiencies

When you join the College of Entropy at 3rd level, you gain
proficiency with Acrobatics, Athletics, and a gaming set of
your choice.

Luck Thief

Also at 3rd level, you learn to borrow a little bit of other
people's luck for yourself. When a creature that you can see
within 60 feet of you makes an attack roll, ability check, or
saving throw with advantage, you can use your reaction to
expend one of your uses of Bardic Inspiration to grant that
creature a penalty to the check equal to the number rolled
on your Bardic Inspiration die. You gain Inspiration that
is usable only on yourself and lasts for a number of rounds
equal to the number rolled on the Bardic Inspiration die.
If you do not expend the Inspiration before that time, it
is lost. Stealing luck, regardless of whether you use the
Inspiration, causes a chaos magic surge.

Infusion Of Luck

At 6th level, when you cast a chaos spell, you cause a chaos
magic surge and regain one use of your Bardic Inspiration.
You regain the use of infusion of fortune after a short or
long rest.

Belief Is A Tool

Everything desires to be something else. Starting at 14th
level, as an action, the luck stealer can change one known
spell to another spell of the same or lower level on the bard
spell list. At the end of the bard's next turn, his or her list of
known spells returns to normal. Using this ability causes a
chaos magic surge.
