Wraith Flash is a Wraith ability in Middle-earth: Shadow of Mordor.
Wraith Flash can be unlocked during the Shattered Memories Story Mission.
It grants the capability to let loose a blast of Wraith power, that stuns all enemies within the A.O.E., when the Hit-streak is charged.
This ability can be used to vacate a combat zone quickly, if one has the Wraith Burn and Double Charge abilities as well.
Note that it also causes a small amount of damage to targets caught in the radius. While the amount is normally not significant, this damage bypasses the "Combat Master" Strength possessed by some Nemeses, allowing Talion to use Wraith Stun and a partial Flurry combo to charge the Hit Streak, then use Wrath Flash, to slowly wear down the target.
It is also very useful when fighting Ghûls.
Trivia[]
In The Bright Lord DLC, Celebrimbor can use his similar power known as "Flash Brand" where he can use the One Ring to brand 2 Uruks within A.O.E. and slightly recharges the ring and Elf-shots.
