"You can now convert clay into soft clay with the Humidify spell from the Lunar spellbook."

http://services.runescape.com/m=itemdb_rs/results.ws?query=clay&price=all&members=

At the moment profit per clay watered is 131gp.
With Steam Staff Humidify only requires one Astral rune.
Profit per inventory = 27*131 - 165 = 3,372 gp
How long it takes per inventory? 10 seconds?
Profit per hour = 6*60*3,372gp = 1,213,920 gp/h

The prices will obviously fall in matter of days, thus taking one more moneymaking method away from F2P.

Lol it takes like 5 seconds to cast himidify… But yeah, soft clay will be like clay+15gp soon :)

^ Seems to be either 4.8 or 5.4.

Hmm I was just coming back to this and was going to fix my clay softener. Clay prices are going to skyrocket (i think), I bought about 45,000 clay 3 days ago and it was slow to buy at max price. I'm hoping not many people will start to use this new way of making clay because then there will go one of the easiest ways to make clay ftp.
Atleast i'll be able to make a profit if I sell all of my clay in a couple of days.

There's already a RSBot script for this, so this will be completely ruined within a week.

It only takes one Astral rune to cast Humidify on the whole inventory? That seems pretty broken to me, though I guess the price fall you guys mention will help make up for it.
