Baiting
The guards and the hounds are dying one after the other without any discrimination, even though they are still trying to run away, they couldn't escape Sam's range that easily.
Sam changed the elemental energy to the earth element and this time used a different technique.
He once again shot the arrow into the sky and it made an arc. While it is descending towards the guards though, its speed is unusually high even by the standards of an arrow.
When it landed in the middle of the group, everyone understood why that is.
*BOOM*
A large explosive sound came as soon as it reached the target. The earth quaked as if a disaster arrived and in case of the guards it is nothing short of it. The ground cracked at first and then each section once again crumbled into its own while the guards and the hounds are still standing there.
