As players unlock and build new facilities for their base, many would stumble across the dilemma over the combinations they should be using for their Trading Post, Factory and Power Plant. There are no exact rules on how one should build them, since all combinations come with different strengths and weaknesses.

This article mainly aim to elaborate the differences between each popular combinations. It would also be a good chance for confused players to decide which suit them the most based on their play style and preferences.

For starter, base facility combinations are commonly mentioned in numbers, such as 252, 243 and more. Each of them signifies the number of a particular facility, with first digit being Trading Post; second as Factory; and third one being Power Plant. So for instance, 243 would mean having 2 Trading Posts, 4 Factories and 3 Power Plants.

Combination 252

  • 3 on EXP Cards, and 2 on Gold Bars; Drone accelerates EXP Cards.
  • Given oversupply of Gold Bars: 4 on EXP Cards, and 1 on Gold Bars; Drone accelerates Trading Post.

Pros

  • Fast in forming the combination with very low cost.
  • Very suitable for early and mid-stage game development.
  • Balanced production of LMD and EXP Cards.
  • Can act as pre-completion of 243 and 153, though not the other way round.
  • Demand on characters with Factory skills are lower than 243 and 153.

Cons

  • Limited power supply, requiring sacrifice on dorm and facilities on the right side.
  • Frequent shift change due to lower Dorm level.
  • Lower efficiency on other facilities (right side), like slower clue collection and lower Friendship Points.

Combination 252 is more recommended for players early on, particularly when Training Room is not required yet. It is more suggested to not upgrade Office in consideration of facilities on the right side cannot be demolished or downgraded. Another useful tactic is to focus atmosphere on one of the dorm, reserving its slots for characters working on Factory and Power Supply.

Combination 243

  • 2 on EXP Cards, and 2 on Gold Bars; Drone accelerates EXP Cards.
  • Given oversupply of Gold Bars: Drone accelerates Trading Post.

Pros

  • High yield with balanced production of LMD and EXP Cards.
  • Quick shift turnover due to max Dorm level.
  • Allow all facilities to perform at max efficiency level.

Cons

  • Lower productivity than a properly setup 252.
  • [Only valid if rushing E2] Limited farming freedom when both Purchase Certificate and LMD instances are active (Thursday, Saturday & Sunday).

Combination 243 is currently regarded as the most balanced and player-friendly setup. It requires little player’s attention to perform at optimal level. In many cases, this would be the most optimal setup a normal player would be using.

Combination 153

  • 4 on EXP Cards, and 1 on Gold Bars; Drone accelerates EXP Cards.
  • Given oversupply of Gold Bars: Drone accelerates Trading Post.

Pros

  • Best yield in LMD and EXP Cards.
  • Quick shift turnover due to max Dorm Level.
  • Allow all facilities to perform at max efficiency level.

Cons

  • Unbalanced production of LMD and EXP Cards, resulting heavy lack of LMD.
  • ^ Require player to purchase Sanity with Originium to cover the gap through farming.

Combination 153 can be seen as an enhanced version of 243, though requiring Originium to operate efficiently. It is a setup meant more for players who are willing to devote their real money into the game. Then again, real whalers would probably work just fine without building base at all.

Base with Combination 333

Bonus Entry – Combination 333

  • 3 on Gold Bars; Drone accelerates Factory.

Pros

  • Faster than 243 in churning out E2*.
  • Quick shift turnover due to max Dorm level.
  • Allow all facilities to perform at max efficiency level.

*Based on the rate that 243 is unable to prepare all materials to E2 6★ in 10 days. While, 333 can produce enough LMD with required materials all farmed within that period (EXP Cards in 5 days and Purchase Certificates in 3 days).

Cons

  • Lower in overall profit, aka wasteful
  • More time dedicated in farming required

Perhaps the most controversial setup ever existed, Combination 333 can be best described as a chaotic version of 243. It has the worst yield per Sanity when compared to 243 and 153, but in return, is able to produce E2 faster as a non-whale player.

Summary

New players are most recommended to build towards 252 during initial stages of game. From there onward, the players can decide to remain or proceed towards other combinations. 243 is generally more favored for players though there is no doubt whalers should opt for 153 instead. If more LMD or E2 is favored, 333 can always be considered. Alternatively, there is also an option for 252 players to try 342 (yes, 2 power plants still) when in the midst of switching to other setups.

In any case, demolished facilities will return all materials. Players should not be afraid to change their setups around according to their needs.
