Fire Emblem Fates Conquest Hard, Paper Mario Thousand Year Door Hard mode.
Conquest is hard enough to be considered Lunatic on Hard i swear its ridiculous. I think im putting this down until a couple months were I recklessly tackle Revelation.
Paper Mario TTYD w/Double Pain badge and no upgraded HP was quite difficult especially in random battles.
The first notable spike was against Doopliss and from there holy moly.
