Most of the undermountain fights are 500 and you can auto battle through nearly all of them even on dark at the speed of light. If you haven't made friendly the two demons yet they're 1800(!) per fight.
Disagree a bit.
TiTS it's easy to get
relatively small amounts of money unless you're gambling. But, money never becomes full inconsequential (again unless you're gambling) due to everything (modding, gearing, ship, multiple quests) needing tons of it. Rocks alone from Zhen'shi's mine would take... a considerable amount of farming that just to buy a single piece of equipment on dhaal. Your first 10k (unless you don't feel like capping stats) is dedicated to either recruiting Ramis or buying a New Texas Gym Membership. Then there's the mods. Oh the mods... Depending on what you want... It costs a bit.
On the flip side money in CoC2 is never really an issue. The only thing requiring much being the wayfort, orphanage, and if you're feeling wasteful, buying everything from Vitruvius.
- TF's are targeted (so you need less) are less numerous, cheaper (barring Nash), and some are free. With the games equivalent to dicksprout being given to you raw in the tutorial.
- The entirety of wayfort is around 9k to 17k dependent on choices
- Nearly all good gear you can obtain are obtained through quests or found
- Almost all training is incredibly inexpensive
- Consumables that are rations or camping supplies are completely unnecessary
Putting my money where my mouth is I made a new playthrough and got to 10.5k at the end of WC. Enough for the wayfort. But, then comes the undermountain... As mentioned it dumps money into you. Just getting to KM put me at 15.5k Finishing the first Celise quest took me from 15.5k to 28k. Doing the second part of Celise quest took me from 28k to 40k.
Enough to clear out the shops, fix the wayfort, renovate the orphanage, TF into whatever I want, learn every power, and still have dosh to spare. On a regular playthrough where people
are doing sidequests it's significantly higher than that. It's part of the reason I talked about the encounter rate so much in previous posts. Them nearly doubling it broke what little economy the game had and made EC near inconsequential.
And so
To answer your question. There aren't any money sinks.
