Guthix page 3

Guthix page 3 can be found as a reward from all levels of Treasure Trails.

The page can then be added to a damaged god book received from the Horror from the Deep quest. There are 4 pages in total.

Once all 4 pages are added to the book it becomes a book of balance, which you can then equip in the shield slot, preach from, or use to bless holy or unholy symbols (50 prayer required).
