Now that we have 3x-Speed Explorers that bring back buffs with a high probability on EVERY search, and usually quite useful buffs at that (all x3 or better) - it's about time that the Skill "Travelling Erudite" gets updated.
Just compare:
Lucky Explorers give you buffs quite often, for free, on every search.
Travelling Erudite is a top skill, requiring an investment of 30 Science Books, and has a chance to return single FISH PLATTERS - or Solar Flares, or or or ...
The only reason to get Travelling Erudite is for a slim chance to receive a Rainbow snow (about once a week), the rest is pretty much discardible.
And Travelling Erudite requires investing a lot of books into skills that the Explorer will not even be using (reduced time for treasure searches / adventures / better loot from treasure searches yada yada).
Suggestion:
Update the "Traveling Erudite" skill:
Turn it into EXACTLY the same special that Lucky Explorers already have: 50% chance to return a buff from the same list that LE's use, on EVERY search conducted by the Explorer.
