Do you need a full group to do dungeons?

A friend and I are doing Zath, we are both 48 and want to do dungeons but we can’t seem to find anyone. Can 2 people tackle a dungeon? And when I say we want to do it, we don’t want to be walked through with a level 80. Sure, that’s super helpful and I appreciate it greatly, but I want to be able to play too!

Depends on the dungeons. If you’re doing a lower level one than maybe, but some dungeons require a certain number.

Black Castle has traps and you need X number to stand in certain spots and the Spider Cave you need more than 2 for the final boss.

On the whole you really should have a full party as that’s how they were designed.
