Do bosses get harder?

I am not a survival player, more like an action/soulslike player and playing V Rising like that too. I am playing solo, made crafting and survival stuff easier from the server settings and focusing on taking down all of the bosses. So far I played for 4-5 hours and having a blast but the bosses are too easy with very little moveset. Do the bosses get harder or they stay the same? Do they also get more fun?
