Sam smiled and waved leslie off. "Don't worry about it," he said, before rolling his eyes as Wilson had one of his little spats, "what a tool," Sam thought to himself as he turned to face the front.
Listening to what Wilson asked, Sam raised his hand. "Well sir, i'd say it's safe to think that every spell could be used as a defensive type one, the best defence is a good offence, as they say. However, i think i get the gist of what you mean," he said, pausing for a second. "Well, in a combat scenario i think that the confundus charm, as well as the disarming and Disillusionment Charm cover a variety of defensive techniques. The Disillusionment Charm takes the approach that avoiding conflict altogether is a good defensive technique," he told the class, "whereas the disarming charm would of course eliminate the threat completely, thus ending any threat on your way." he said, before moving onto his third technique. "And finally the confundus charm takes the most direct, offensive approach, wipe out the threat altogether and incapacitate it from rearing back up," he told thhe class. "Really, what i've covered is more the techniques you could take, not the spells, as there are literally hundreds of options to take there, those spells are really the three that would represent the three main methods of eliminating a threat and defending yourself in a duel." He concluded on the defensive side of things.
"On the offensive side it's a little trickier than that, most spells can be used in an offensive nature, and are intended to be so, however there are a few that i suppose you could use that aren't intended for offensive purposes. Perhaps the tickling charm could be an example, where the aim of the spell is to tickle, probably a prank sort of thing, however it could be used to effectively take out or distract an opponent in combat, i think. Like i said, it's a little more complicated trying to find offensive spells that aren't intended to be offensive," he concluded, hoping his answer had sufficed
