Modding question

Hello all,

I'm trying to balance or change the runes we get on level up, but for that, I need to fully understand the script, so here it is (mage level_up part):

// ïðîêà÷êà
level_up {
leadership=40,30
attack=1,10
defense=1,20
intellect=1,40
mana=6,40
rage=4,20
runes=7-7 // ×èñëî è âåðîÿòíîñòè ïîëó÷åíèÿ ðóí. Íå èñïîëüçóåòñÿ â 1.6.
rune_might=20
rune_mind=20
rune_magic=60
book=1,5 // ðàñòåò íà 1 êàæäûé 5 óðîâåíü
}
k_spirit_up=0.5 // êîýôôèöèåíò íàáèðàíèÿ îïûòà ñïèðèòà
}

So I suppose the 20/20/60, is the maximum number of runes we get from leveling in the entire game.
But how or what represents the 7-7 ?
The cyrilic after that line translates to this: "Number and probabilities of reception of fleeces. It is not used in 1.6", so I'm guessing it's the total number of runes we get at each level up, divided by the 3 types of runes, but how does it get divided or how exactly does this work ?

Any help is appreciated.

And another question, is there a way to add a spell to our spellbook, or add an item to our inventory, just checking :p ?

Greetz,
