An F-Rank Archer? Each Arrow Gives Me 100 More HP

The whole world has been digitized, and at eighteen, people can change class.

Song Wu becomes an F-rank archer, which means he can't avenge his parents.

Luckily, he has a divine skill.

[Divine Skill: Body of Heaven, Rank: ???] [Note: Unique]

Effect 1: Each normal attack that hits grants 100 health.

Effect 2: Arrows have a chance to deal true damage based on his own health.

Effect 3: When he kills an enemy, he instantly restores health equal to the damage that enemy dealt to him.

More effects unlock as he levels up.

At level 30, every 100,000 health grants 1% attack speed.

At level 100, every 100,000 health grants 1% critical damage.

Every arrow he fires grants him 100 health.

Song Wu goes completely arrow-crazy and starts firing like mad.

He enters a dungeon. The boss sees an archer whose health bar reaches all the way above its head, and falls into deep thought.
