OK, I'm looking for help building out some homebrew right now, would love to see if anybody knows of any existing homebrew or systems that can point me in the right direction.
The idea is that I want to allow a player character to pick up a massive object, like a wagon, and throw it as a super powerful ranged AOE attack. Running with the wagon example, the idea is that the PC is throwing the wagon in order to crush enemies beneath it. I don't want to just do an attack roll because then it doesnt engage with the wagons size enough, nor do I want to engage with the improvised weapon rules at all. But whenever I try to lean into the unique functions of the attack it begins to get too bloated and overcomplicated to use.
The biggest reason im having so much trouble is cus i dont want it to just deal damage. I could just make it an AOE the does some bludgeoning damage, but then what happens to the wagon? Does it just disappear, or break, or just get put aside? No, I want to think up some effect that can literally have enemy creatures get crushed under the wagon, and need to get out from under there. And the hard part is that this attack needs to be adaptable; its not just wagons that the PCs will be throwing, but also boulders, large monsters, trees, barrels, couches, and all sorts of other stuff with a range of sizes. No need to sort out the whole feature here ofc lol, but any pointers could be awesome just to help me stir my creativity
Its a long shot but does anybody have any ideas or resources that could help me build this homebrew?
