Doesnt seem intentionnal. The burning tome which gives less offensive bonus than the black book is worth ten times more. They both are 2 stars items. Burning tome +1 +1 2500 Z Black book +2 +1 240 Z Seems weird.
Actually, the Black Book does nothing, but the Burning Tome let's every enemy you hit (melee at least, dunno x-bow) burst into flames. So it's pretty decent. Also, iirc, Black Book is 1 star, Burning Tome 2.
Oooh was wondering, thanks. Black book is still awesome for the beginning if you're into necronomics ! 2 additionnal damage on every hit is not negligible too. Love those
You're right, I meant: no extra spell being auto-cast when you hit something with melee-attack. It's not actively doing anything. Like casting a spell. It just gives those bonusses passively. But I totally agree it was worded clumsily
