The second golden Skill Book was different. It was a Skill Book that increased casting speed, capable of eliminating the pre-cast animation of any Skill, making it instantly cast.
This kind of Skill Book is exceptionally powerful for the Mage profession or any profession with long pre-cast animations.
Indeed, it could even be described as game-changing.
Especially for the Mage profession, many forbidden curses are incredibly powerful, equivalent to a nuclear bomb when unleashed!
However, the casting time for these forbidden curses is generally not short.
If such an instant-cast golden Skill were paired with them, it would be truly terrifying.
If used during a sneak attack on an enemy's main base, it would be utterly devastating.
However, to prevent such incidents, Anti-Forbidden Curse Formations are established within safe zones.
These can forcibly counteract a forbidden curse once detected.
