Don't bother leveling up Simon if you want to get the best ending. It takes up too much time and the endings are dependent on the clock. Another tip would be to forgo getting the thorn whip and just go for the chain whip instead, but I guess you are past that part.
Yeah, I'm already well past the point of no return when it comes to getting the best ending. Already took up three days, and the best ending is for beating the game in a week, wasn't it?
I already grinded for the Thorn Whip, White Crystal, and the Holy Water. I'm in the second town, whatever it is. There's a church there, so it's not that unlucky one that happened to not have one.
AFTER CASTLEANIA I WARNED YOU NOT TO RETURN
Not gonna lie, I laughed hard when I read this.
Also, thanks for the welcome backs, everyone

EDIT: Since I'm not really trying for any ending, I'm just gonna grind a lot. How much experience do I need before I hit LV2?
