It's not exactly
"Patched" all they did was make it harder for you to get the
tokkul. Now you can't sell them in very large quantities.
I had to learn how to this too but haven't used this to many times...
My way - Get a couple of
uncut dragons stones and multiply the number of
uncut dragon stones with
980. That will tell you how many
tokkul you need

That's the part where you learn how much tokkul you will need to buy the
dragon stones and transfer.
Example:
I want to transfer
1 Million Gold Coins to a level 3 from a level 138.
The level 138, that's giving the level 3 the
one million coins buys
20 Uncut Dragon Stones.
1 Uncut Dragon Stones = ~
50,000
20 x
50,000 =
1,000,000

How to get the
Tokkul:
You learnt how to calculate the amount of
Tokkul you will need to transfer by now but if you don't here's more calculations -
1 Uncut Dragon Stone =
980 Tokkul
The Uncut Dragon Stone is worth
50k remember that...
20 Uncut Dragon Stones =
19,600 Tokkul
This explains how you can get the
tokkul now -
Buy a few Body/Fire runes and sell them to the rune shop in Tzaar for about
2 tokkul each.
You'd have to sell 9,800 Body/Fire runes to get
19,600 Tokkul which would be enough for
20 Uncut Dragon Stones.
Another way -
Buy a few Chaos runes and sell them in the same rune shop in tzaar for
9 tokkul each. By doing this you get the
tokkul much faster

Sorry for the Black Font for Tokkul I just used it but it didn't turn out too good....
