Dedicated weapon / gear

M.C Valentine; extra stat is attack. +1~2 max bullets; at turn end with 0 bullets, gain 1-turn crit-damage buff (3-turn cooldown) and +1 TP; unique effect loads Magic Bullet at 0 bullets (2 rounds base, up to full magazine at 5th Awakening). Crucially, at 3rd Awakening the weapon skill adds "at action end with 0 bullets, gain an extra attack or skill use," which enables LTK Christian's burst mechanism. This is why Christian's dedicated weapon at 3rd Awakening is treated as his true body. Armor: defense is useless (paper), so stack crit rate/crit damage. Hero grade: Assassin set; Legendary: Crow-motif Raven set. Accessory: Ancient Hero's Ring is best (dealer staple). Arrowhead works for Rapid Fire/Suppressive Fire but not for AoE (Barrage/Indiscriminate Fire); Fang usable for attack but physical penetration only applies to combat attacks so not ideal for AoE mains; Whetstone is meaningless since Confirmed Kill isn't an extra hit. Hero grade: Wound Aggravation charm or Golden Dice for crit. (No explicit S/A/B tier rating present in the source; only class-level labels like "finisher class" / "true body" / whale-only character.)
