Invention and T2 production are excellent avenues for players to earn money in the industry profession.  Unfortunately, the systems and process is extremely daunting at first glance. Once you understand the mechanics and thought process, though, T2 production can be an excellent ISK-generating endeavor.

But what happens when you plateau on building anything but ships? There are pretty hard caps on maximum investment and returns per character because of time bottlenecks. Pair that with misconceptions and startup costs with large investments like ships, and invention can seem like a much smaller operating market than it actually is.

This is where decryptors play their role. Essentially, these items augment the resulting BPC and the chance for success. Decryptors can help improve efficiencies on expensive BPCs, or reduce attempt-costs for smaller batches. Odyssey also added 3 new decryptor classes and unified the naming scheme for these items, making them even easier to use.

How Do Decryptors Work?

Decryptors can augment two things.

  1. Probability of success

  2. Resultant BPC stats

So, first you change the chance of winning, then you change the actual prize.  Since invention is already a “weighted coin toss” probability, decryptors just change the probability of success, rather than do any strange probability modification.  The specific math can be a little sticky, but tools like EVEHQ’s Prism tool will let you toy with the final results.

It’s important to note what the resultant BPC will be, and subsequently what the decryptor will do to the final T2 BPC. All invention returns -4ME/-4PE T2 BPCs by default (regardless of T1 BPO/BPC ME/PE), and can return anywhere from 1-10 runs depending on a few different parameters. A quick rule is: modules/ammo/drones usually yield 10-run T2 BPCs, ships/rigs return 1-run T2 BPCs as “max runs”. Then the +runs modifier will be applied to the result T2 BPC, depending on whatever the pre-decryptor result would be.

Also, decryptors are always consumed 1 per-attempt, unlike datacores, which vary by blueprint. When accounting for decryptor use, you need to account for probability of success along with result T2 BPC runs. I personally use the following to boil down the costs in the final product per-unit cost.
