Telluric Shock is a powerskill which launches the player up and in the direction of his movement and then promptly dives towards the ground, triggering a wave of stone spikes on impact in a way that mimics the same attack by the Hand of the King.
Using the skill makes the player jump into the air, and then smash the ground, releasing a wave of spikes at the point of impact, traveling through the ground outward from the player, dealing 150 base damage to the enemies it hits.
The spikes will travel over the course of 0.3 seconds.
Using it while standing still will simply make the player jump in place, but using it while moving will cause a jump in the direction of movement. It functions in a similar way in the air, but will only cause the downward smash, without the jump.
