03 · HOW TO PLAY

Playing this build

1Early preparation

With Blade, do not force normal attacks through an entire combo; mix in sheathed defense. Collect attack speed equipment in advance.

2Upgrades and transition

Rendblade: Heavenrend can use Great Iaido Slash at 100% Sword Strike. Evolving into RuinDance activates Barrage instead of Great Iaido Slash, so switch to sustained normal attacks.

3Combat loop

  1. Reach 100% Sword Strike through normal attacks.
  2. During Barrage, use the four-hit normal combo and the additional physical hits between attacks.
  3. Break the combo before the enemy counterattacks, then re-enter to prepare the next Barrage.

Boss fights

Land Barrage's repeated hits during openings with little movement. Do not always try to finish a long combo; leave immediately when a dangerous pattern begins.

Without the core items

If Barrage is hard to trigger reliably, improve attack speed with Warrior Seal and Sword Training Manual. If groups are difficult, consider Red Mist as a support item.

04 · REVIEW NOTES

Cautions and scope of verification

Conditions to watch

  • RuinDance cannot use Great Iaido Slash. Focus on continued normal attacks during Barrage rather than one wide strike.
  • Barrage's extra hits are based on 75% of physical damage. Strengthen them by increasing physical damage.

Needs further verification

No specific unresolved issues are listed. This does not mean performance has been verified in actual play.
