blood walk...

[Socratov]

In complete arcane (p26) we have the blood magus. for a defensive caster a quite nice option, but the capstone is actually brilliant. apparently a bloodmagus can enter a creature to be transported to anywhere on the plane.

Only 1 question: do you have to busrt forth in the same round you enter a creature?

assuming you can delay bursting forth... let's talk abuse:

sneaking into one of the partymembers, bursting forth out of the BBEG or one of his henchmen (obvious use)

but what about: having a vial of blood of a NPC, threathening him into behaving, or you will find him.

finding a fugitive after obtaining his blood...

so, any more abuses?

This reminds me of Dragon Age with the mages and the blood vials they have to take should the mage go AWOL...

Its a really cool ability though.

You should read the novel Bloodwalk.

The ability is cool, and I love the PrC in general. But I don't think there's much in the way of abuses possible with it.

You could conduct some copyright infringement by re-enacting the movie Alien for the townsfolk.

It says right in the description of Bloodwalk that it all occurs in one standard action.
