Beverly squinted at Elmer the Enchanted Elm tree then switched her gaze at her wand. This kept going while she flexed her wand wrist. She wanted to ensure that Elmert was in good hands -- who was she kidding, of course it was! She already practiced the incantation enough to feel comfortable to cast the spell. That only left the second part of it, which was the wand movement.

No proper wand movement and BOOM or simply nothing.

The Slytherin did not want any of those outcomes--or any outcome that wasn't the outcome she wanted. And she wanted the perfect outcome. Flexing her wrist some more, she paused and focused on her wand.

All it took was three small anti-clockwise circles. That was a whole lot simpler than getting the incantation correct for this snakette. Either way, she practiced it a few more times. Three cirlces. Anti-clockwise. Three. Anti-clockwise.

BAM.
