The first skill when not ascended have 25% to give 2 random allies 50% attack for 2 turns, when hero is ascended to 3 stars the skill is improved to provide 50% attack to all allies for 2 turns. Unfortunately, even if the description is upgraded, when proc the skill still gives bonus attack to just 2 random allies.

Please check and fix this.
