Effect: Tickles and weakens

The Tickling Charm causes the target to buckle with uncontrollable laughter, weakening them and potentially incapacitating them temporarily. This laughter can disrupt the target's focus or actions, which can be useful in various situations.

History

The Tickling Charm has been documented as a life-saving spell on numerous occasions. Its ability to incapacitate or distract can be employed strategically in various scenarios. Rowan Khanna noted its practical use in saving lives through its disruptive effect on adversaries or situations requiring a non-lethal intervention.

The incantation *Rictusempra* comes from the Latin "rictus," meaning "the expanse of an open mouth," and "semper," meaning "always." Together, the spell's name roughly translates to "always laughing," reflecting the charm's effect of inducing persistent laughter.

Casting and Effects

The charm is typically cast with a specific intent to cause laughter. It is particularly effective against individuals who are already vulnerable or distracted. 
Beyond causing laughter, the charm can weaken the target, making them less effective in combat or other tasks. It is noted for being a non-lethal way to neutralize or delay opponents.

The charm is often employed in duels or situations where a less aggressive approach is preferable. It can also be useful for breaking up conflicts or creating diversions.
