B-Level Arcane Skill, Second Stage Advancement

Apart from the aforementioned enhancements, a prompt appeared before Sterl's eyes—

[You have successfully advanced to the second stage of your arcane skill. Since your arcane skill is at B-level, you can choose one of the following four additional bonuses.]

[Physical Enhancement: Gain an effect—30% additional damage reduction from Constitution.]

[Mental Enhancement: Gain an effect—30% additional casting speed and magic damage reduction from Mental attributes.]

[Strength Enhancement: Gain an effect—30% additional resilience and toughness from Strength.]

[Agility Enhancement: Gain an effect—30% additional movement speed, slow resistance, and evasion from Agility.]

[It has been detected that you did not choose an enhancement when advancing to the first stage of your arcane skill for unknown reasons. You may now choose two enhancements.]

"There's even an additional boost??"
