The main thing that needs to be buffed here is simply increase the amount of bundles we get from finishing the scroll. I think even going from 1 bundle to 3 would actually make these scrolls a decent source of caphras. As it stands the voodoo scrolls are the worst in the game, and i believe it's simply due to only getting 1 bundle as a reward unlike all the others that get 5.

Until they added the stone to put in more scrolls, they were actually pretty chill to do.

But it feels like that update also made the single scrolls harder, even if you summon them without the stone.

So I stopped doing them.
