Monster Book Quest for those who don't know.

So what is the quest and what does it do? 2x exp? :f6:

If so, how long?, any monster?, is it repeatable?

EDIT:

That comes from when you collect 5 of a monster's card.

When you do this quest it takes away that bonus, so what Isaac is saying is that it's better to lose the exp boost from the Snails or any other lower levels monsters rather than the Skelegons.

OH!

So what's the quest details? lol
