We're playing Waterdeep: Dragon Heist and we
just got our mansion.
I play a gnomish Artificer/Wizard and want to build my workshop
in the mansion's basement. But it's quite small for what I have in mind. Digging seems not to be a viable option to expand the basement, because the ground is pretty hard.
What kind of spell, non-magic or half-magic solution (ie. machines) could do the trick? I come from 3.5e. Back then there were several midlevel options to do that. Stone to mud + Mold Earth. But there is no Stone to mud, or I am not finding it.
Maybe here's someone who had the same idea and made it work or you just know a way to make it work. I'm very curious about how you achieved this.
FYI Our DM is pretty liberal and let's us do pretty much, so feel free to stretch the rules. I don't talk about home-brew, but RAW is not that important with this one: RAW answers are preferred though.
The basement is carved into stone and around 6 by 4 squares big and around 10ft high. I'm thinking of doubling it in size... ie 6 by 8 squares. There are no special constraints besides the stone, which is (according to my DM) "not as hard as granite but still pretty hard". We're playing Dragon Heist very loosely interconnected and can do with our time, whatever we want. The whole campaign is about one year long in-game, so to use that space the time frame should be around one or two months. So I'm not necessarily looking for a quick solution.
During this campaign, we will end up with level 8-9 (according to my DM). I plan to have 2 levels of wizard and the rest in artificer. 3rd level spells is the maximum level that I will be able to cast during this campaign.
Right now, I'm broke, but I'm pretty sure that it'll change in the near future. This goal is more of a long term thing anyway as I already mentioned.
I ask for general possibilities besides the obvious: Just dig, Dude! At least if it's not the only possibility. If plain digging is the only way, it's the only way and I have to dig or let someone else do the digging. Feel free to list all the possibilities that there are in the game or mention some examples out of experience when you tried to accomplish a comparable task.
