Magic Spells Can't Melt Steel Beams

So rogues pick locks and, in the past, they've disabled traps. (I hope that makes a comeback.) Mages light veilfire torches, blast through barriers and raise magical bridges. And warriors ... kick in crumbly brick walls.

That takes strength, no doubt, but it's also kind of lame. It begs the question as to why your mage can lift boulders with magic but can't deal with shoddy brickwork. (Also, who the hell is walling up these treasure rooms? FOR THE LOVE OF GOD, MONTRESOR!)

But what could a warrior do that a rogue or a mage could not? I've thought about this for a while and could not come up with anything ... until an old Conan the Destroyer clip showed me the way.

Warriors bend bars.

Imagine, if you will, if certain entrances (and cells) had bars over them. The warrior can use their strength to just bend them so you can slip through.

"But why can't I use my maaaaaagic?" Simple answer, sparklefingers: the metal bars are either crafted or enchanted to resist magic. If you were in Tevinter, that's EXACTLY the sort of precaution you'd use to protect, say, treasure rooms from thieving mages (or just regular thieves). Only a warrior has the strength to bend the bars.

It's an idea I'm putting out there.
