I've noticed that in the Index section it's possible to click on the number of entries unlocked, which reveals some clickable bonuses based on the number of entries unlocked in the Index. So far I only have 160 entries, and my available bonuses are for 50 and 100 (it tells me that another bonus is available at 200). When I click ro receive the bonus, all I get is a conversation with Doc for each bonus.
I'd like to ask if anyone with a higher amount of entries has any information on other better bonuses for getting entries in their Index and if they could please share.
Sorry for the long post and thanks for reading! (:
