Guild Wars 2

Well, I am a Norn ranger, and it seems as if my “Call Owl” skill is not working :S
I use it, yet nothing seem to happen :S

Hum… I have not tried the skill, but what are you expecting from the skill? This is not summon skill like the call wurm, this is a straight offensive skill. So you have to cast it at an enemy, and it will place a bleed on it:

Call upon an owl to attack and bleed your foe.

Damage: unknown
Bleeding: 20 s (850 damage)
Range: 1,200

Yeah i know, but its not working… nothing happens

It works for me.
Check if you/your pet have any bleeding attacks besides CO utility.
