The Beast Tamer in Harry Potter

Wands: The most important component of a wizard's combat power.

They are made primarily from branches of trees inhabited by Bowtruckles. The wood is treated through an elaborate process, then combined with materials produced by magical creatures such as dragons, unicorns, Veela, Thestrals, and phoenixes.

Potions: One of the major sources of income for wizards.

Polyjuice Potion uses powdered Bicorn horn. The main ingredient in Strengthening Solution is Re'em blood. A Jinx-Reversing Potion requires a Softclaw lobster. Veritaserum uses Fwooper feathers.

Magical artifacts: The ultimate trump cards Aurors use to turn the tables.

The lenses of Ghost-Detecting Spectacles are made from the eyeballs of Darklight Ghosts. The Secret Flame Ring is set with Ashwinder eggs. The Anti-Curse Suit is lined with the scales of Chittering Bugs.

So...

Mastering Fantastic Beasts means mastering wealth and power!
