I’ve played a lot of D&D over the years. Hundreds of hours.
But these so-called “dungeons”? No captives. Not even any cells. That’s not a dungeon. that’s a glorified cave.
And don’t even get me started on the dragons. Dragonborn? Sure, I’ve seen plenty. Heard my fair share of Draconic. And wyverns are fairly common I suppose but that’s like pointing at all the dogs in the world and saying “we’re infested with wolves!”
I’m beginning to feel like I’ve been lied to all this time.


Off the top of my head:
There are a lot of ways to deal with this, you just have to get creative and maybe set yourselves a short side quest or two to acquire what you need for the real job. Half of the above suggestions can be accomplished by a single tactically minded cleric, and no arcane caster worth his salt isn’t going to know how to fly by level five, wizards that can’t fly generally don’t live very long and sorcerors that can’t fly don’t get laid.
