While being a way to counter enemies in PvP, the ECP consuming hold mechanics can be used to enter Over Strike Mode, though it will be most likely slower than just using 2 ECP using skills.
Thanks to Frenzy, when used in Over Strike Mode, you can consume the entire ECP acquired again, despite still being in Over Strike Mode, refreshing the Over Strike buff duration.
As long as you have ECP, this skill's key can be held down infinitely.
This skill can be used as a panic button in certain cases (where invincibility does not save you from taking damage) due to providing high amounts of Received Damage Decrease.

The skill is based on DFO's shared Ranger skill Gun Guard, which does not feature a counterattack when hit from behind and simply reduces damage the same way as being hit from the front.
