Hi everyone,

I tried to search for something like this but couldn't find it so I did the "math" myself and thought I would share it. Probably I am not the only one obsessed with codex and boosting my meta in this game to increase my stats further. I found a codex cost/rank for Calypso but have not found for other planets. Currently I am more or less living on Cyrene so I have thought about how to finish codex on all mobs and how best to match with missions (e.g not finishing codex on a mob before you need to kill 2,000 of them) and so forth. I initially set up an excel-document with all 43 creatures on Cyrene and have tracked which rank I am at but have not known the cost per rank and also costs for coming ranks.

I think many of you already know some of these findings but I will write them anyways for the curious mind:
  1. Codex reward is linear to cost (except repeatable) and also different skillset rewards (e.g Skillset 1 = Aim, Skillset 2 = Perception and so on..) have a fixed exchange rate (as seen in table 2).
  2. Even though the cost for the same rank between different mobs are different, it follows the same logic by multiplication of the cost of completing the first rank.
As seen below in Table 1, the cost for finishing rank 2 is twice that of the cost of finishing rank 1. Rank 25 is 100 times as expensive as the first rank. In table 1 below we can see that finishing rank 10 on the codex for a mob, although being 40% done with ranks in absolute numbers, still only means that you have spent 9,18% of the total cost it would take to finish all ranks on this mob (not counting repeatable).

Table 2: Also, by looking at first rank repeatable codex we can see the cost and reward for each skillset (since first rank repeatable codex is 5000 PED cost and gives 25 PED Aim as reward).
SkillsetExample Skill1000 PED cost rewards with skill TT:
1​
Aim
5​
2​
Perception
3,124​
3​
Alertness
1,562​

So, how then to translate this to know the actual cost for each respective mob rank? Like I wrote above, codex TT reward is linear to cost (except repeatable missions). And since we know the exchange rate between the skill categories (e.g Aim, Perception, Alertness) and also the cost and reward for first repeatable rank we can use this data. If you look at the rank you are on a mob and also see the reward and which skill set reward it is, you can just follow the example below:

Example: Rank 10 Living Storm (Cyrene mob) gives 2,5 PED Alertness reward (skillset 3). In table 2 we can see that 1k ped cost equals 1,562 ped reward of Alertness. By dividing 2,5 with 1,562 we see that the cost for this rank is 1600 PED. By looking at table 1 we can see that Rank 10 is 16 times as costly than rank 1 which means that Rank 1 would cost 1600/16 = 100 PED to finish. Rank 25 costs 100 times Rank 1, so the cost to finish Rank 25 on this mob be 10 000 PED. We could then use the same logic to fill in all the other costs for missing ranks.

So how could this information then be practically used? By knowing the cost of each respective ranks for each mob, you could filter and finish the cheapest ranks first. Also it could guide you to know how much PEDs would actually be needed to complete codex on a specific mob.

Here is also a chart to visually show the cumulative cost of finishing each respective codex rank:

Kind regards,

Edit:
Got this doc in a PM shortly after my original post. It has mobs from all planets and the costs seems to be accurate. It also includes the skillset type of reward. Credit to Aeolus who seems to be the author :)


As for my original post, I guess it only serves to show how much more difficult each rank gets. I will keep this thread with this link in case anyone in future searches for the same thing as I did originally.
