History of Banshee's Wail

Overview

Banshee's Wail is the intrinsic of The Lament, an Exotic Sword. Holding the aim button revs the blade, which increases damage and adds Shield-Piercing to all attacks, which makes it useful against Barrier Champions. Revved attacks build stacks; stacks raise heavy-attack damage and damage resistance. At full stacks a heavy attack spends them for a large hit.

Sources disagree on the exact input, one saying [Block] and another the aim button, and the stack details come from Beyond Light-era guides. Check the in-game control prompt before relying on a specific binding.
