Elden Ring Earthshaker Guide, Notes & Tips

• This is an Ash of War Skill, associated with the Ash of War: Earthshaker.
• FP Cost: 10 on use, 5 on follow up.
• Deals 36 stance damage
• This Skill is not Chargeable
• Upon activation, the user holds their armament (weapon) with both hands above their head pointing to the ground, before thrusting it directly into the ground. Then they plunge the armament, creating a medium-sized shockwave around them that staggers enemies.
  • After the shockwave, the user can input a Strong Attack to make a follow up attack that sweeps over a wide arc, which can be aimed in any direction.
  • All three instances (thrust, shockwave, and follow up) consume stamina separately.
  • The thrust and follow up attack deal the same damage type as the weapon while the shockwave deals standard damage.
• The ground thrust has a hitbox and deals the same damage as a one handed light attack.
  • The shockwave deals approximately the same damage as a two handed light attack.
    • Sometimes it seems to deal about 30% more damage for unknown reasons.
  • The follow up attack deals approximately 10% more damage compared to a two handed light attack, and causes knockdown on some enemies.
  • All of these attacks provide above average poise/hyperarmor.
• Follow up attack can be done slightly later than the recovery animation suggests.
  
  • This can prove useful as a feint, or to delay the follow up attack when the enemy is in range.
• If used without FP:
  • Does not produce a shockwave.
  • Loses aditional poise.
  • Deals less damage (50% damage penalty).
  • Consumes more stamina (50% more).
