Monster Bookworms

I'd basically never get an exp buff or card buff at all.

The way they work you barely ever get them anyway... I grinded 114-126 on my Night Lord at Newties and only had one hour of exp bonus, at around level 122. Each level was around 3-5 hours on 2x exp so that's at least 45-50 hours of grind. I looted 7 cards so far..

IMO it should be a permanent buff after you get the 5th card, or keep giving you the buff on each card you find after that, I mean if the point is that you learned all the monster's weaknesses, why would you forget after an hour .-.
