Actually his odds of getting +3/+3 to two level 1 skills on an ilvl 1 head are as good as you'd ever get for any two skill combo. On ilvl 1 items, you have an 80% chance of any one staffmod being a level 1 skill (20% of it being level 6). As you go higher, more skills become available, so that chance only goes down.

On a given reroll you have a 30% chance of 0, 40% of 1, 20% of 2 and 10% of 3 skills. So you have 30% chance of getting at least 2 skills.

On a 2 skill head, the chance of the first skill being RS or SM is 32% (80% that it is a level 1 skill, and there's 5 of those, of which 2 are what you want) and the chance of the second skill being the other is 20%, for 6.4% altogether. You have triple that chance on a 3 skill head (three possible pairs). So all up 3.2% chance of getting both RS and SM on an ilvl 1 head (or wand for that matter, the process is the same).

Not too bad so far. The bad news is that any one skill has only a 10% chance of spawning +3 (60% will be +1, 30% +2). So to get both of them +3 worsens your odds by a factor of 100. So all up the odds of +3 RS/+3 SM on an ilvl 1 wand or head is 1 in 3125.

You could of course get much better odds by accepting less than +3/+3.

I'm not trying to dishearten you, just to make it clear what you are facing.
