Stats Guide - Attack Speed

The Attack Speed (or "AS") stat reduces the animation time of your skills’ execution.
It will also add extra hits on channeling skills but won't modify their charging time*

Note*

This stat becomes especially strong at high values coupled with Shorter Cooldown, and even more for some classes with powerful/numerous channeling skills (like Erwin, Stella, or Lily).

Note

In case of a choice to make between stats to add, this stat proportionally wins in strength among other multipliers in terms of long-term fights.
