Nowhere, you gotta DIY them. Just like with houses and, you know, civilization in general.

Aren't stalactites made of soft material? Just pickaxe your way beside the door. Heck, an axe may work if you don't mind destroying it in the process. If you have spell for creating water somehow, use Roman technique of making a campfire against wall, letting it warm up and the splashi g it with water to crack it. There's so many ways to be a menace to DM xD

aw shoot


Or just knock. Not the spell, literally knock on the door.

We don't exactly have a lot of time for that though because a war is on

It was sealed with magic (I had detect magic going) and no handles, locks or visible seals

No lock, no handle, how does it open?

Look, I get it, it's embarrassing to try and pull a push door. It doesn't mean it's witchcraft. Just try pushing!

So the door itself had a sorta embossing design of an incomplete web. You would have to complete the webbing but there is a trap part that, if connected, triggers active, offensive traps. With a good investigation roll, my arcana and a Web spell from the rogue's cloak, we did the puzzle and the door opened itself

Best guess? Directly above hollow stalagmites. ‍️

credible enough

The dwarven lockpick (Adamantium hammer) is an adventuring staple for a reason; its fun and empowering to pick locks barbarian style.
