発射弾数アップ

Increases the Amount (projectile count) of the socketed card by +1. More projectiles means more hits per play, dramatically boosting total damage output.

• Effect: Amount +1
• Type: Amount Gem
• Stacking: Each additional Amount Gem adds another +1

• Magic Wand: Already hits multiple times; more Amount multiplies its already-high output
• Knife: Extra projectiles let you hit multiple enemies simultaneously, improving wave-clear
• Runetracer: Each bouncing projectile deals damage — more Amount means exponentially more coverage

• Might powerup: Every additional projectile benefits from Might, creating multiplicative scaling
• Double Damage Gem: All extra projectiles from Amount also deal doubled damage
• Critical rate bonuses: Each projectile rolls its own crit, so more Amount = more reliable crits

Amount is one of the most impactful stats in Vampire Crawlers. This gem is almost always worth socketing regardless of build.
