I cant have multilate and prepareation becuse i need be lvl 70 or??? help me please!!!!!

To have mutil. you need 41 points
To have prep. you need 21 points
For both you need 62 points, but at lvl 70 you can have only 61, so... sory mate. You cannot have both.

With new ext. you will be able to gain lvl 80, so u can get another 10 points :)
