XRA-9

A crossbow that reactivates magic with its last round

01 · SETUP

Starting setup

Availability depends on your unlocks

Recommended character

Ghost

Ghost uses spellbooks without consuming MP, making cooldown reduction easier to exploit. Final weapon damage decreases by 40%, so invest in spell damage rather than the crossbow. Weapon special attacks still require MP.

03 · HOW TO PLAY

Playing this build

1Early preparation

At the Colossal Crossbow stage, compensate for reduced final weapon damage with the starting Fire Arrow. Cast the MP-free spells as they become ready, mixing in normal shots safely.

2Upgrades and transition

With M-9199, learn piercing shots and bullet condensation. With XRA-9, use the last normal round as the timing for reactivating magic.

3Combat loop

  1. Use your main spell first to start its cooldown.
  2. Spend the last round through normal firing to reduce the current remaining cooldown.
  3. Cast the ready Grimoire again and reload to prepare the next last round.

Boss fights

Empty the magazine during safe firing windows against the boss to reuse spells. When using condensation, check the weapon's special attack cost separately and distinguish condensation itself from actually firing normal shots.

Without the core items

Without Meditation Book, gain Haste with Mage's Coin and Rylie’s Pocket Watch, and cast spells during safe openings. If you obtain a strong Grimoire of another element, you can change your main spell using the Elementalist's elemental damage bonus.

04 · REVIEW NOTES

Cautions and scope of verification

Conditions to watch

  • The 25% reduction applies to the cooldown remaining at that moment, not the original full cooldown.
  • Spending the last round is crucial, so do not assume increased magazine count always triggers the effect more often.
  • Ghost uses Grimoires without spending MP, but weapon special attacks still require MP.

Needs further verification

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