Learn how to defeat the challenging Knockrock boss in Lost Sphear. This guide covers its attacks, weaknesses, and strategies for victory, along with post-boss events and rewards.

Walkthrough
  1. 1
    Boss Fight - Knockrock: Knockrock can inflict petrification with Fossilize; use a Panacea or Sherra’s Refresh to cure it. Avoid Mythril Gun and Damascus by positioning characters in a square pattern (melee to sides, ranged to bottom corners). Wait out Shiny (magic defense) and Steel Wall (physical defense). Oreikhalkos deals around 200 damage to everyone. Knockrock is weak to wind attacks. Before finishing the boss, fully heal your party as its final attack, Divide, can deal 300+ damage.
  2. 2
    Post-Boss Rewards: After defeating Knockrock, you will gain the artifact knowledge: Fairy Wind, Deus Ex, and Akashic.
  3. 3
    Collect Terromite: Inspect the glowing red spot at the northern end of the room to obtain Terromite.
  4. 4
    Bobboulder Encounter: A Bobboulder will appear. These enemies explode upon defeat, so ensure no characters are nearby when they are finished off.
  5. 5
    Mine Escape: Retrace your steps back through the mine, avoiding the Bobboulders. A counter in the upper right corner starts at 5. If the counter reaches zero due to Bobboulder explosions, it's game over.
  6. 6
    Return to Elder: Once you exit the mine, return to the elder on the eastern side. Speak with him to receive the Show Tuner, a weapon for Sherra that halves the MP cost of her skills.
  7. 7
    Next Objective: Your next destination is the Lunar Kiln in Graccia.
Tips
  • Positioning is key: Melee users on the sides, ranged users in the bottom corners.
  • Heal petrification immediately using Panacea or Sherra's Refresh.
  • Exploit Knockrock's weakness to wind-elemental attacks.
  • Fully heal before Knockrock's final attack, Divide.
  • Be extremely cautious when defeating Bobboulders to avoid the counter reaching zero.
