Although the sheer aura coming from Gistella's body kept rising to a ridiculous level, the decision of using the Berserker's Curse skill is something that she regrets almost instantly. It's her blunder to use a skill that she doesn't really know except for Rex's bestowed skill.
Roar!
Rex sneered seeing Gistella's eyes explode right after she used the Berserker's Curse skill.
The Berserker's Curse skill is a skill that will increase the physical prowess of the user exponentially but it comes with a cost, the cost of using this skill is that the user can't regenerate at all. It blocked every healing or regenerative ability.
Since they are Werewolves, terrifying regenerative ability is their core power.
With the White Omicron aura that Adhara is emitting right now, any Werewolf that doesn't have a Royal Bloodline or is accepted by a full moon will find their entire body suffering immense pain and their eyes exploding into meat paste.
