How many law runes from 31-45 mage?

How many would it take teleing to lumby?
Then at 45, teleing to Cammy till 50?

 

It is 1.1k Teleports to Lumbridge to 45, and 718 Camelot Teleports from 45-50.

 

runehq.com has a good calculator for this.

 

any cheaper ways besides teleing? and not raising hp.

 

Cursing is cheaper, but takes longer. Much, much longer.

 

yeah as stated above cursing is cheapest way to lvl up mage but takes a while and the clicking gets pretty annoying... you can try low laching i guess? but its a real waste of money.

 

meh ill just spend 500k on laws :/

 

yeah in the future just use http://www.tip.it/runescape/?page=magic_calc.htm

 

Thats what I used to get my calculations (first post) lol.
You should curse if you don't want Hp xp. If you do, then I suggest Crumble Undead on Skeletons in Varrock Sewers. Very good xp.
