Guild Wars 2

after 26 kills it should summon a fleshreaver.
Yes, 1st time you get this reaver but after 26 more kills you get nothing.
Even after 100 kills nothing happens.

I must seriously ask, is there any Superior Sigil or Superior Rune full working as described?
I spent much gold ony to see at the end it’s bugged. That makes really no fun.

This rune works until you die. Then you must logout to get it working again.
Its a one-time-sigil!

Steal health does not work but more important :
Mist form does not work, you get still damage
