History of Flash Counter

Overview

Flash Counter is a sword trait that emits a short-range blast when you block damage after raising your guard. The blast disorients nearby targets. The wiki dates it to Season 10 as a Legendary trait.

The wiki describes the effect as melee blocked immediately after guarding disorienting and weakening the attacker, which differs from the in-game description. The sources checked give no range, duration or damage figures.

Swords

It rolls on many Swords, including Aurora Dawn, Just in Case and Thin Precipice. Abyssal Edge was the first sword to get Flash Counter, and it pairs the trait with Redirection: blocking incoming damage creates a blast that counts as hitting enemies, which grants Redirection stacks without using ammo.
