Big fan of the romhack! Honestly, it's really refreshing to see a difficulty setting this high- it makes me look at the whole game in a completely different way. I love preparing for all the old dungeons in new ways- trying to predict what the new suprise boss is, new mechanic at the end of the floor, etc.
My favourite was the surprise boss at the end of Quicksand Cave- it encouraged me to kind of shake up my team comp, using Cacturne to get through it easier.
Still, i'm at the end of Temporal Spire and i'm near-out of reviver seeds. I really want to get to the end of the game and do the Darkrai story without dropping down a difficulty setting- i'm worried that i've either got to pick between turbo-grinding for $2,000 Reviver seeds to get through TT, or potentially ruining my post-game experience by dropping down to Difficult.
Is there any passwords to swap from Difficult back up to Hardcore pre-Darkrai?
