Guild Wars 2

I tried it out today in PvE and PvP. When I press f2 there should be a buff given to me like thieves get when using their venom elite. The timer goes right on cooldown and nothing happens. No stun, no immobilize (wiki says it’s bugged to immobilize instead of stun), no nothing. I really wanted to try out the pet specifically for the f2 stun as it would greatly help me out, but alas it does not work t my knowledge.

its on the pet and it is only one attack if said attack misses or if it times out it will not apply
