Mana Bone

Description
[Low Rank Magic Affinity, Low Rank Magic Accumulation, and Low Rank Magic Tracking skills have compounded and evolved.]

[Low Rank Mana Bone Lv5 (Passive)]

[Originally, humans were organisms that did not welcome mana, and through their strong tenacity as well as their talent, they realized a method to harmonize with mana. In order to more perfectly handle the mana that spread throughout the body as it pleased, the mana is accepted, created, and circulated by an imaginary organ that covers the heart. They called it the mana heart.]

[However, you are a skeleton without a heart, so you have done something outrageous and substituted the mana heart with your entire boney body. That scale is truly enormous, and if you did not have a considerable understanding and handling of mana, it would've been impossible to even attempt.]

[By achieving a balance between the vast knowledge, your talent in mana, and the special situation, this astonishing skill was born, and no one besides yourself knows the growth potential of this astonishing skill.]

[The invigorated flow of mana increases the body's reaction speed.]

[The invigorated flow of mana shortens the activation time of all skills.]

[The Low Rank Mana Bone skill has become Lv10, and evolves to the Intermediate level. Your understanding of magic deepens, and you can more effectively store more mana into your bones. The power of your mana increases as well.]

[The Intermediate Mana Bone skill has become Lv10 and has evolved into the high rank level! Magic has increased by 200! You can proficiently control mana with just your mind, and can now more easily manipulate the surrounding mana. You can now  react more perfectly to any type of attack that involves mana.]
