yeah, the one in varrock castle u just need about 7-9k for 1k bodies, get an earth/water staff (probably water, ill explain) the earth runes are probably the easiest to craft if u got money , then buy earths at 8-10 ea or waters at 12-15 ea monsters also tend to drop higher amounts of earths then any other rune I used this from 30ish to 55. If you're a member, get a mud staff and just buy a ton of mind runes. The only downside of this is that sometimes, if you wield a staff and cast, the success rate is higher than if you use purely runes, and so every now and then, you have to wait for the spell to wear off.
