I would've shot you dead with a Meteor for that stunt, in a pure 'Rocks Fall, Everyone Dies' moment. It's gamers like you that make DM's come up with insane ways to kill characters. ☄ You know, like that whole Tomb of Horrors thing... 👀
Then honestly you're looking at it wrong.
A trapped door is a challenge for the players to overcome. It might involve the rogue spending an hour (game time) to roll the dice on detecting traps, disarming traps, picking the lock, and so on. It might involve the wizard pulling stunt like that. Either way it is a challenge. The issue with the "a wizard did it" that actually bit us in the tail was the other players assuming that the door was "defeated" the minute it tipped over. So the barbarian in the party rushed in.
.. which meant running across the
explosive rune trapped surface of the door ..
Reasons to fully explain a plan to the party before implementing said plan +1!
Ranting against the barbarian aside, in effect I turned one big challenge the party couldn't really deal with into multiple, smaller ones that had their own risks. Once the door is down we
still would have had to disarm the magical traps or use grappling hooks, rope, and a lot of strength checks to pull it out of the way. That would mean backtracking through the dungeon. (I was planning on using Grease spells to get around some of the noise.) Go figure dragging a heavy, metal door across a stone floor is going to make noise. Cue handing the GM a perfect opportunity to roll for random encounters because noise attracts random encounters. Note this is after tipping over said metal door onto a stone surface..
Had the door been mechanically trapped instead of magically trapped the only thing that trick would have done would be to let the party get well out of range of any traps before pulling on it. (50' of rope, a grappling hook around the exposed edge, and a corner work great!)
And, oh yes, we still would have had to move the heavy stone table out of the way to start the process of moving the door. That's not just a strength check - that's going to involve some dexterity or more clever thinking to get the table out of the way without touching the door and setting off the traps. (Can you throw the grappling hook and catch the table leg but not over-shoot and hit the door?)
There are ways around these that require effort and creative thinking (Silence 15' Radius to keep the door tipping over from ringing the dinner bell for anything nearby, Grease spells, and so on) that burn party resources. The ranger lost a spell slot for their Silence spell. All of those things being used on a door make the rest of the dungeon harder.
