Lowest level with a skull sceptre?

When I've got fed up suiciding my pures against this, I shall just take my old main in, keep running back to the monastery to prayer recharge, and so on... full rune against the rest, full green against the catablepons.

For the ankous, time to lay several crumbles on them before needing to eat.

The problem with lower levels, is that with lower hitpoints and low defence, you are eating all the time (unless you can keep snatching the door, eat, return and re-attack) - got nailed a couple of times at the door, carrying enough runes for several trips - must remember to PACK LIGHT!
