|Ga-Derg & Ga-Boi|
|Weapon type||Spear and Short Sword|
|Native skill||Soul Gauge Vamp|
Ga-Derg & Ga-Boi is Hilde's strongest weapon in Soulcalibur IV. It can be bought in Character Creation for 22,000 Gold after completing Story Mode with Hilde. It has Soul Gauge Vamp equipped by default as a skill, which randomly decreases the opponent's Soul Gauge, allowing the player to absorb part of it by pressing A+B+K simultaneously during a fight.
It bears a slight resemblance to Corsesca & Broadsword, another of Hilde's weapons.
