Hmm... Light magic drops quite often, did they change the chance to 4%???
They even wrote in the changelog that the chance of Sorcery dropping was reduced from 8% to 4%, and the chance of Attack dropping was increased from 2% to 6%.
They must have made a mistake. They meant Sorcery, but made it Light. Attack was indeed increased to 6%.
And, by the way, there were cases when Light magic wouldn't drop no matter what... :(
Yes, here's the information from the resources (although the engine seems to be cutting off some parts, so I'll remove the symbols...):

Горящие реки сходили с ума, пытаясь остаться водой,
Земля пропустила коварный удар, раскрывшись на шаге вперёд,
Взлетел разъярённым драконом Огонь и понял, что тоже умрёт...
