What Thunder Edge does
Blade Sweep hits add 20% Storm Surge charge per foe.
Thunder Edge is a legendary chest item that raises Thunder Edge for Blade Sweep only. It lasts for the rest of the run. One copy is all it needs; extra copies do nothing.

How to get Thunder Edge
Chest items drop from treasure chests out in the wilds — spend gold to open one, and each chest costs more than the last. Rarer items are rarer drops, so Luck (from Fortune or the Censer) makes a legendary pull more likely. On every floor’s plaza the Wishing Well grants the exact item you name once per floor: the surest way to complete a build around Thunder Edge.
Skill
Thunder Edge and Blade Sweep
Blade Sweep
A wide sword strike in front of you that can knock foes back.
Without Blade Sweep in your build this item does nothing, so take the skill first and wish for the item once the skill is upgraded.
