Are you asking for tips in your dungeons? Or are you expecting unsolicited advice?
Even new players sometimes like to learn as they go.

Kylki, you make it sound like you expect mentors to know everything and that they must supply this information to you in advance. Nothing regarding the mentor system makes one am expert. They're just going to be somewhat more familiar with the subject. Almost every dungeon cam be summed up as "kill the things, don't stand in colours.". If there's a specific mechanic you encounter and we're unsure of, all you gotta do is ask! Even if the mentor is unsure of an answer, that isn't a crime.

Please stop holding mentors on this lifted pedestal. I mean I'm one myself and while I love to give answers where I can, it's strange to see how dependant others can get on this.
