1.You only have the 50% buff on the path. It can be used as an escape healing ward+path+cloak+cloak and of you go.
2. No the dps is very small and so is the hps . It can be used as a good ultimate generator for trial bosses where your group stacks if you have high crit chance due to crit heals. It add some dps (~40 maybe) also if you keep it up.
