Ultimate Gley

Gley Ability Overview In The First Descendant

Gley is a vampire-esque characterinThe First Descendant. She switches between two states to consume HP, deal damage, and then recover HP as she defeats enemies. This playstyle can make her quitefragile on the battlefield, especially if you don’t pay attention to her abilities.

Here’s what each of her abilities do:

Casting most of her skills consumes HP. Having too little HP will prevent you from using the skill.

Best Gley Build In The First Descendant

The core of this build is toloop Increased Sensory with Massacre for constant infinite ammo. It’s primarily aimed at dealing with bosses in Void Intercept Battles, but you can also use a Launcher, and take this build into a dungeon. To achieve this seamless loop and deal decent damage, this buildrequires a lot of investment in Gley and her weapons.

Best Modules For Gley In The First Descendant

Modules in this build focus onlowering skill cooldown and increasing skill duration, ensuring that Increased Sensory has a 100% uptime. This is followed byModules with statsthat increase raw ability damage, like Dimension Skill Power Modifier and Non-Attribute Skill Power.

TheTranscendent Module in this build is Massive Sanguification. While it doesn’t directly affect Increased Sensory or Massacre, it allows you to instantly gain the necessary Power of Life stacks to activate Massacre, even when there are no enemies around. It also offers an additional source of survivability.

Effect

Massive Sanguification

For mobbing, you can focus on Skill Range instead of Duration to empower Massive Sanguification. However, it won’t be as good asFreynaor Bunny in content like 400% Infiltration Operations. Ultimate Gley with Explosive Life is a far superior option.
