Hemopump

The hemopump is a deathrest building added by the Biotech DLC that allows Hemogenic deathresters to store more hemogen.

Acquisition

Hemopumps can be constructed once the Deathrest research project has been completed. Each requires 100 Steel, 4 Components, 5 Hemogen packs, 5,000 ticks (1.39 mins) of work, and a Construction skill of 4.

Summary

Active hemopumps require a pawn capable of deathrest and must be connected to a deathrest casket. As a pawn deathrests, it consumes 100 W of power and ? hemogen packs per day. If the deathrest is not interupted, the hemopump increases the amount of Hemogen the pawn can store by +25 until the next deathrest. A hemogenic pawn can store 100 hemogen before modifiers.

Like other deathrest buildings, a hemopump permanently binds to a pawn once used, with no penalty for deconstruction. Deathresting pawns have their own separate limit to the buildings they can connect to, which can be increased with a deathrest capacity serum.

Analysis

A hemopump will increase the amount of Hemogen a Hemogenic pawn can store, allowing more uses of their abilities before needing to bloodfeed or consume a hemogen pack. Most of these abilities are related to combat.

Whether this is useful compared to increasing move speed or decreasing deathrest time depends on playstyle, though the boost is modest either way. While a few additional uses of abilities like Coagulate can be very useful, the other options tend to be a larger priority. In any case, you must be using at least 80 hemogen between refills for the hemopump to have a noticeable impact. As starting capacity is 100, 80 hemogen must be consumed before you lose access to the most expensive abilities (which cost 20 hemogen).

Hemopumps are one of the few deathrest buildings without a connection cap, so can be used if a pawn has a high building capacity and the other buildings have reached their caps. It has a small niche for long caravans, extending the time where conceited noble pawns with Hemogen Drain can last without bloodfeeding or facing penalties from eating hemogen packs.

As with all other deathrest machines, these cost a non-negligible amount of steel and components. Consider holding off on building them until you are more well established and are able to produce steel and components reliably with deep drills and fabrication benches.
