Wondering if this run is possible

A run from sunspear sanctuary for a char who has not yet gained access to desolation, by a char who has access to wurms, to bone palace

Nope, you can't use Wurms if there's a player in the party who hasn't unlocked them yet. I tried it once.=P

Not sure if its still possible, but you used to be able ot reach vabbi via the desolation. Just have the player without a wurm go out of compass range or die then the runner can enter his wurm.

you still can do it.but as said above u need get out or radar and die.
you can get to vabbi and all locations there that way w/o do quest.

but if you want enter into bone palace you cant.even if the person running you have the quest for enter bone palce active ,you wont be able get in urself.tried already...cept if they changed it

You can get into the Bone Palace this way but you have to have someone with the quest "A Deal's A Deal" in the party and actually complete that quest. We learned this the hard way when running my Mesmer there for her Ancient Armor.
