Bell of the Dead!
A standard Necromancer skill.
A black cover, adorned with reliefs of skeletons and a bell tower.
This book is predictable enough; it's definitely a reward tailored to my profession.
Judging from its effect, it's quite similar to the Priest's [Mirage Choir]. After 'choir' is released, a phantom choir appears in the air, affecting targets within range.
The difference is, the choir enhances the living, suppressing necromancy.
This skill book enhances necromancy and suppresses the living.
Essentially, if another profession has it, I must have it too.
When I first became a Hero, I was indeed desperately in need of skill books, inquiring through various means, even trading with mages for skill book readings.
Back then, despite having the rank of a Hero, my attacking methods primarily relied on modern weapons.
But now things are different; since mastering the ancient skill [Water Drawing Technique], ordinary skill books have greatly reduced in appeal for me.
