Where can I get Ender pearls (Minecraft)?

Hey guys and two I have the following question:

I want to defeat the ender dragon without having to switch to gamemode 1.

I've already found the portal, but I'm missing the ender eyes.

For this you need Lohenstaub (I've already collected enough) and Ender pearls.

Where can I get ender pearls quickly, apart from having to look for an endermen every night?

You rarely see it and it doesn't always drop one. And there were no pearls in the chests of the portal fortress.

Are there any special (farming) tips?

As far as I know, Enderman are now spawning in the Nether in the Warped Biome. You can farm them there.

Depends on the version, from 1.13 farm with the Fletcher Emeralds and then hit the pearls at the Cleric, from 1.16 over the Piglins.

Yes, they spawn but the drop rate feels like 1 in 100, then trade better

Sword with Looting and then farm… With Looting sometimes two pearls drop… And one mostly… Then it's fast… And as Dultus already writes, in the Nether in the blue biome…

With Looting Enchantment it's quick

With Looting, it's actually very quick.

Yes, but if you don't have a lottery, trading is faster
