Make toming safe after a prayer

[Forward]

If for some  reason we could pay for better luck I would want to know what I'm paying for.

Currently the community have no idea about any "drop rate" in the game. I would want to know the chances tomes have before and after I put gold down a drain.

Maybe you get 1 wraiths if you would get 3 without a prayer. Or 0 if you would get 1, which would make this ability 100% safe on Hard (why would you waste money on Hard, but whatever) and still risky on Rag.
