Guild Wars 2

So it stack 12 vulnerability instead of of 3 is this as intended or bug?

It bounces, if there’s only 1 enemy and 1 ally, it will apply 12 vulnerability, it applies 4 vulnerability per hit, and first hit doesn’t count as bounce.

Nope, working as intended! I love it when it bounces like that and I can just pop focus 5 and epidemic and spread it to everyone. Gotta love that focus.
