Showman (Charisma)

Presentation is at least as important as being effective,
if not more so. After all, there is little reason to do
something unless is looks impressive. You gain the
following benefits:
• Increase your Charisma score by 1, to a maximum of
20.
• You gain proficiency in the Performance skill. If you
are already proficient in the skill, you add double your
proficiency bonus to checks you make with it.
• If there is a non-combative audience watching you
fight, once per turn, you can gain a bonus to an ability
check or attack roll equal to the number of people
in the audience, up to a maximum of your Charisma
modifier. You can use this ability three times, and
regain all expended uses when you finish a long rest.
