Tectonic Slam is an attack skill that slams the ground in front of the player, dealing area of effect damage in a cone. Each attack has a chance to consume an endurance charge to deal more damage and gain a larger AoE.

Skill functions and interactions

Endurance charge consumption effect: When you have a number of Endurance charges greater than your minimum endurance charges, using the skill has a 35% chance of consuming it, adding 60% more damage to this use of the skill. Below is a visual comparison of the skill effect first without and then with consumption of an Endurance charge. Using Multistrike Support with this skill tries to consume an endurance charge on each of the three strikes for a total of three charges consumed per activation of the skill.
