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.

Now consumes an endurance charge every third time you create a fissure, and gains 5% more area of effect and +5% branching fissure chance per endurance charge. The spread of fissures has been partially-normalised, ensuring both sides of the main fissure will get at least one branching fissure. Now deals base damage and has an added Damage effectiveness of 180% at gem level 1 (from 170%), up to 220% at gem level 20 (from 200%).
3.7.0	Now deals base damage equal to, and has an added damage effectiveness of, 170% at gem level 1 (from 130%), up to 200% at gem level 20 (from 160%). The length of the primary fissure is now 36 (from 32). The length of the secondary fissures is now 15 (from 22). The width of the first secondary fissures is now 7 (from 8). Now has an attack speed multiplier of 80%.
3.5.0	Charged Slam (which typically consumes an Endurance Charge) now deal 60% more damage (up from 18%). Now has a 35% chance to consume an Endurance Charge to create a Charged Slam (down from 100%)
3.2.0	Added a new Strength Skill Gem - Tectonic Slam: Slam the ground with your weapon, unleashing a fiery fissure in front of you, dealing area damage and releasing a random number of smaller fissures branching off from it. If you have Endurance Charges, one will be consumed, maximising the number of fissures. Requires a Mace, Sword, Axe, Staff, or Unarmed.
