Nightblade is a class in The Elder Scrolls Online. Nightblade is tailored to benefit assassins and players who prefer a stealthy approach. There are three known skills governed by Nightblade; Assassination, Shadow, and Siphoning.
In-Game Description: Nightblades are adventurers and opportunists with a gift for getting in and out of trouble. Relying variously on stealth, blades, and speed, Nightblades thrive on conflict and misfortune, trusting to their luck and cunning to survive.
The Assassination skill is orientated towards melee attackers, particularly dual-wielding, with abilities ranging from increasing your attack speed to teleporting to your target and damaging them at the same time.
The Shadow skill is orientated towards self-preservation, with abilities ranging from inflicting fear on nearby enemies to becoming invisible and some crowd-control.
The Siphoning skill is oriented towards spell-casting assassins, with abilities that de-buff and damage enemies and provide healing and positive buffs to you. These abilities range from decreasing nearby enemies’ attack power to casting a damage-over-time spell on a target that casts a healing spell on you for the same duration.
