Drop rate increased?

So i did some searching today for the rarest drops in game (preferably the dlc) and was surprised to learn that the Lizard Greatsword has 0.5% drop chanse?

And that the Black knight armor set has 1-2% chanse per piece to drop? Thought the full set can dropp as well but that's basically 1 in a million. Basically just winning the loot lottery.

Well I remember clearly the first imp in fog rift dropped the sword for me.

But even stranger, the whole Black knight set dropped on literally the first enemy as well. Not just 1 piece or anything like that. Every armor piece dropped. (I kinda thought it was like that for everyone, that one of the mobs had a 100% or something)

So either I won the lottery or drop chanses have been increased?

It's basically the same story when it comes to the flame monk sword, but I actively was going to farm him, but got it the first time. I even got a second one because i died further inn to the dungeon..

I had to farm a whole 15 minutes to get 2x Magma Blades in Volcano Manor

The grossmesser I have like 10x already.

I got 2 Beastman curved sword without even knowing

I have 3x Ripple crescent halberds without knowing

2x Halo scythes without even knowing

And it's basically the same with every other weapon that's less than 2%.

My point is that either I'm lucky or the drop chances cannot really be as low as down to 0.5%?
