I don’t read many of them, but in the RPG theme I can recommend Goblins! (https://www.goblinscomic.com/comic/06252005)

And, well, while it’s not quite a webcomic but more a series of mostly unrelated skits, there’s always good old Oglaf… It’s quite hilarious, but uh huge NSFW WARNING just in case you miss it : https://www.oglaf.com/cumsprite/
