i doubt it's a typo cause the Starting Life in Re:Boot World event gives you 500mil when you get a character to 180, coincidentally the exact amount for a box. I don't really care if the medal is in reboot or not cause it's still rng based to get it. To me the problem is more towards the amount of random junk that are added to the boxes (surprise and random box) that has nothing to do with the crossover.
This makes little sense. The ring was originally in the list b4 someone ninja edit it out and if it was not intended to be in the books, it shouldn't have been obtainable in the first place. If you fixed the skill than why would need to remove it from the rewards to monitor it (the only problem with the skill is not knowing the 2nd hp bar value)? Instead of keeping the ring in the book and benefiting philosopher book sales, your helping dupers make more profit.
