I kept my body in a downswing position and stared at the tree twig that
was about 5m in front of me. However, there was no signs of the tree
twig breaking even after the effects of the skill disappeared.

This was to be expected. The basic «Slant» range was 2.5m at most.
The power would not be able to reach a place twice the distance away.
