Best part is they can stealth while on fire
Flare only reveals stealthed targets. They can stand right in the middle and cloak right back up again. Why did ZOS even make the skill? Its garbage. Also if you use a detect pot and you hit a NB that is spaming cloak, you will do ZERO DAMAGE. They get 100% immunity to everything for the durarion of cloak even while detected.
The skill is over the top and NBs are being proped up by the most OP skill in the game.
