I've seen people meleeing dust devils etc. for slayer while using a bunyip and DFS.
Your not suppose to meelee Dust Devils??????
bunyip is way enough to stay healty,you might aswell use a rune defender for faster kills
Been tested, you kill faster with DFS because the +attack stuff on RS really doesn't do much, for some reason +strength is better than +attack (where as it should be the other way around, accuracy > strength).
