I moved on to Act II without finishing the Bestiary, but I got to 854/1K after spending about 200 more lives in the wilderness after reaching (and turning back from) the final Act I scene. I had 349 Insights and only 5 elemental techniques (all mono) after all that. So I had over 30% of the insights and only 9% of the techniques. I don't mind that there are so many, and I'll look forward to circling back to the Mortal Realm later, but I still wonder why my chances for techniques was so bad after getting my first one as the second insight in a region.
