We've been running instances lately, and this is really the only time I notice having to use Rebirth within a given amount of time. Once the player releases spirit or the 6 minutes is up, my Rebirth button gets greyed out. Does this mean I cannot rez them once they release spirit? When I find the corpse, it does not give me an option to rez if they had released already. I wasn't sure if the ghost needs to be around to rez, which poses a problem in instances since the body recovers at the entrance. I have only noticed this in instance situations, because in normal battles I can usually rez way before the timer runs out. I have been searching this question to no avail. I think I am missing something here :P Thanks for any help :)

You can rez them always . They can relese spirit that's not important . If you are druid CD is 30 min . You need seed and that's it . Of course you have to find body always and rez it there .

I think there is a targeting bug that doesn't let you cast on their portrait after they release, but if you find the actual corpse, you should be able to cast on that, you have to be pretty close.

Just a clarification to whats already been said......

In order to rez someone after they have released, you need to cast rebirth first....THEN target the remains.

Also becarefull if you cast your rez on them just before they release (aka: they are at thier loading screen) your rez will be lost and they will not recieve it.
