i was wondering where you can get raise the dead scrolls as the only way i can raise dead at the moment is at temple(which is really annoying if i'm not near any),iv'e just started chapter 3

There are no such spells to be bought in BGI. There is a priest spell for tis but it comes at a very high level.

In SoA there are both rods of ressurection and raise dead scrolls.

If you are really strapped you can use a cheat code scrl63 to get the raise dead scroll.
