[edit] Acquisition

When used against Charr, the Ebon Vanguard Assassin can perform up to two attack chains with a moderate Ebon Vanguard title rank. When used against other foes, the Assassin can only perform a single attack chain.
Unlike allies created by Summoning stones, it's possible to have more than one Assassin in area.
This skill works very effectively after using "You Move Like a Dwarf!".
The Assassin is not infused
When the Assassin's summoning period ends, it appears to Shadow Step into nothingness.
Although it is not considered as a summoned creature, it is still counted as a creature being created for the skills Spirit's Gift, Explosive Growth and Boon of Creation.

Assuming the Assassin is able to complete his combo, this summon has the highest consistent damage output between the five of the reputation governed summons.
