From the Super Mario Wiki
Being that they are some of the final enemies encountered in the Pit of 100 Trials, they have very high defense and attack. They have many different attacks, all powered by magic. The most common attack of an Elite Wizzerd is to fire a laser, which does eight damage on either Mario or his partner; it can also pierce through any defense badge equipped. Other common attacks caused by Elite Wizzerd are its ability to tickle with their hand, — which does eight damage — as well as their lightning storm, which does same damage as tickle and laser attack.
Elite Wizzerds also have the ability to improve their stats, rather than attacking. Elite Wizzerds can make themselves Huge, increasing their attack by two, they can increase their defense by three, and restore their HP by ten. They also have the ability to make themselves dodgy, invisible, and electrified for two turns. They even have the ability to cure softness caused by Mario or his partner. If alone, an Elite Wizzerd will create four copies of itself. These copies cannot be damaged, nor can they attack; they are merely created as a diversion for Mario and his partner. If the real Elite Wizzerd is found, the copies will vanish for the rest of that turn.
Elite Wizzerds are one of the toughest enemies in the game (even by Pit of 100 Trials standards), given their high attack, high defense, and ability to make copies of themselves. However, like most enemies on Floors 91-99, they are quite vulnerable to Flurrie's Gale Force, which is by far the easiest way to beat them.
