Strikethrough

While wielding a Two-Handed Weapon, or while wielding a Bastard Sword or Dwarven Axe in your main hand and a Shield, Orb, Rune Arm, or nothing in your offhand, your attacks can Strikethrough. When your attacks can Strikethrough, every attack has a chance ("Strikethrough Chance") to hit an additional target.
 * Strikethrough Chance begins at 20% while considered Two Handed Fighting (which can be improved through feats and enhancements)
 * If your Strikethrough Chance is over 100%, you will always attack a second target (if in range) with a chance to attack a third.
 * If your Strikethrough Chance is over 200%, you will always attack a third target (if in range) with a chance to attack a fourth.
 * If your Strikethrough Chance is over 300%, you will always attack a fourth target (if in range) with a chance to attack a fifth.
 * If your Strikethrough Chance is 400% or higher, you will always attack a fifth target (if in range).

Strikethrough was introduced in Update 45 and replaced Glancing blows.
