Phases & Attacks:

  1. Phase 1: The King uses basic spade-themed attacks, including projectiles that fly across the screen and ground slams that create shockwaves. Focus on dodging and building TP.
  2. Phase 2 (Low HP): The King becomes more desperate, using larger, faster attacks. He'll summon chains of spades and perform wide-sweeping attacks.

Strategy:

  • Pacifist Route: To spare the King, you must reduce his HP to near zero (but not defeat him) and then have Lancer intervene. During the fight, focus on defending and using Ralsei's 'Heal Prayer' to keep the party alive. Have Kris use 'ACT' to encourage Susie, and have Susie use 'Rude Buster' to lower the King's HP. Once his HP is very low, Lancer will step in and end the fight.
  • Violent Route: Simply reduce the King's HP to zero using FIGHT attacks and Susie's 'Rude Buster'. This is generally faster but misses out on some narrative nuances.

Rewards: Progress to Chapter 2, and a significant amount of money.
