Two base purchases are confirmed. The health station is the seat you spawn sitting on. Plot expansion adds mosquito slots when the base is full. Both are bought with in-game cash at the station, not from the weapon menu.
Seat forms players actually bought
The order below is the sequence two sessions purchased. It is not an official poster.
- Chair, level 1. You start with it. The station already shows that it can be upgraded.
- Toilet, called toilet IV. Regain was described as "a lot more blood." A player also planned to take the toilet to level three, so levels exist on a form.
- Bathtub-shaped hot tub. Both sessions put about 15,000 cash on a mid-chain step. One player counted from 8,000 up to "almost at the 15,000 needed" and received the bathtub shape. Another called 15,000 the way to get way more health. Do not paste 15,000 onto every tier.
- Bench, 40 health per second, read off the prompt.
- Couch, 80 health per second. One later upgrade produced another couch.
- Bed. It was purchased, and a line about leveling the bed implies further steps. The per-second number was not stated.
A vase appears in one fight-guide description of the same chain and is missing from the other. If your prompt shows a vase, that is your station, not a contradiction you need to ignore.
When the seat is the right buy
Buy the next seat form when either of these is true:
- A boss you can already damage still kills you. The broom versus a 2,000-health mosquito failed until health was higher.
- A better hatch drinks you dry before 100%. Regen has to keep up with the mosquito, not the other way around.
Weapon damage does not refill blood. Cash for the seat comes from fed mosquitoes collected at the green circle.
Plot expansion
Expand when you are out of slots. After a Clown hatch, a player asked whether there were enough slots and expanded "just a little." Later the base was full again while deciding what to keep. The price was never shown; it is on the prompt.
One progression note says weaker mosquitoes can be benched in a dungeon when you expand. The button for that was not filmed, so treat the dungeon as reported, not as a mapped menu. Retiring a weak common after a stronger hatch is the pattern both sessions ended on.
Update V3's public text says the base fence area was expanded and offline earnings were added. How offline earnings pay, and whether the fence change replaces plot expansion, is not in the filmed sessions. Use the prompt in your current server.
