I think you mean two things. ;)
She had two good things, which were useful in the one thing...
Alyssa Milano good for two things....
1) Solving a Diophantine Equation, sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. (source: Popular Mechanics .com)
2) Absorbing a large amount of arcane political data and coming to an astute analysis for which millions of fans seek her out. Such as: “Throw Trump in jail for life.”
Unless you meant something about her looks. Can’t be.
