Uragar could do everything in the safety of his lab and record the final result in his pages, ready to be conjured at a moment's notice. The cursed book had spent countless hours revising the diaries of the Lost Magus and improving his craft beyond Zavra's wildest dreams.
Once a Source Spell was inscribed in his page, Uragar could study its effects just by looking at the strings of runes and alter the parts he found lacking. The only weak point of Source Magic was that it required performing many complex calculations and consumed lots of mana in the middle of battle.
The Book of Knowledge had no such problems. He performed his spells with no rush and stored them in his pages days before a fight actually took place. Spells that Zavra could only hope to achieve through practice, luck, and intuition were a walk in the park for Uragar.
