god books and god staves and high level magic

hi guys, id like to brig up the topic of god staves and books? I feel these are needed as a lot of people have sufficient number of pages for full books (I myself have enough for 3 books) and god staves!! these are so needed!! what if we had to do some tasks to acquire these?

I have also been trying to cast vulnerability, enfeeble, and stun, and even when wearing rune gear I still cast it!!! if have 4.5k casts I needa o for exp and this wont be possible if I always hit the spell as it cannot be repeated, anyways my magic was -68 on posts ive read is -65+ is supposed to never hit so yeah :\
