There are two ways to cheese a boss fight; you either use the game's world against the boss, or the game's mechanics. In Crimson Desert, it's a bit of both. For instance, cheesing the archery contest requires you to place floating cores in the right spot, and another boss cheese requires you to slam tree trunks on top of them. Both of them use traversal mechanics and things found in the game's world of Pywel.
However, if there are no trees around, it seems there is another way for you to cheese boss fights, perhaps those found in the Abyss or other such areas. It's pretty simple, actually, but requires a bit of preparation. All you need to do is get some bumblebees, release them, and not get hit while they do the work.
As showcased by Zephryss on Twitter (via Gamers Club), if you come upon a boss that you're struggling with, and there will be a lot, you can release a few captured bumblebees which will do steady DOT damage to them. Of course, it will take some time to deplete their health bar, so you can't just stand around doing nothing.
You can find bees around beehives...
