And yeah, I hate when you get defeated by a final boss, specially when you have to go over an entire dungeon go get to it and you can't save.
Bit it's really sweet when you win at the first try
Just don't make my mistakes. You know those special dungeons in every RPG, where there are super strong enemies, super cool treasure or weapons, or whatever, don't train

beat the final boss first. The final fight loses completely all the excitement when you're overleveled =(
