Epitasis is the addition of a concluding sentence that merely emphasizes what has already been stated. A kind of amplification.
Example:
Eat your sandwich. All of it.
Anesis is the opposite of epitasis. It adds a concluding sentence that diminishes the effect of what was said previously.
Examples:
The little dog is cute and obedient. That said, he smells like a polluted mud flat at low tide on a hot afternoon.
The employee was smart, efficient, and generous. However, his temper was off the charts.

I agree with Ms. Royce. I’m not sure I’ll remember the name of the rhetorical device, but I’ll darned sure remember the impact it carries. Thanks again, Julaina.
