Ridill is 20 ATK, but similar requirement to Blue Rose...

Both are 'end game' tier of Swords, but Ridill might the the 'rapid attack' type without a animation?

Also some weapon stats are bugged or wrong, a Tier 1 8 bit coin rapier has 52 ATK but upgrading it reduces it to 32... LOL.

Ridill hits 3 times (visually only one slash though). Its damage ends up a tiny bit higher, but Blue Rose has elemental on its side. Very much a matter of preference, neither has a huge advantage.

I don't think it's a bug, the upgraded version probably has elemental/status effect or is much faster/hit multiple times

I started Hard mode and notice the 8 bit weapon like that...
It has no elemental.

ridill is better for attack spam because it hits many times
blue rose is better for techniques because of its higher base stats.
