Abyss Farming for Blind Prophet?

Hi, first forum post here. Getting back into POE1 for the new event and planning on going Blind Prophet for my build. I think it'll be cool to specifically do an Abyss Jewel character.
Idk what the average market for abyss jewels is, but I assume I'll need to play a lot of Abyss to farm my own supply of abyss jewels. So on that note, does anyone have any good ideas for abyss farming?
I never played much Abyss in endgame and I'm sure there's guides available online, but wondering if anyone had some event related information. My market information is POE2 skewed rn, but I assume stacking flat dmgs on the abyss jewels is meta, especially with the increased base crit chance prophet gets.
