Sadly I am not that far in the game to be searching for rare blade but it gives me something to look forward to eventually! I see you have great posts about gaming :) I love Nintendo!

One thing I will say. For this game, None of the Rare blades are bad. Matter in fact. You can beat the main story, and beat the post-game super bosses with any rare blade. its just that some are better then others. so if you dont get Percival in your playthrough dont worry about it. there are a ton of rare blades in this game and ALL of them are useful in their own ways.
I'll check out your discord thing. and thank you for the feedback.
