The skills are slowly ticking over and the BPC coming in – so it is time to get a little more serious.
For T2 Invention attempts you need:
. The required skills
. A blueprint copy of the T1 item
. One specific data interface
. Two specific types of datacores
. Access to an invention slot
Optionally, you can also adjust your chances and the end BPC attributes with:
. A named T1 item that you are researching for
. A suitable decryptor
I also probably helps to assume things are not black and white – as Serpentine Logic’s comment to my last post suggested.
I will start with the T2 Small Tractor Beams. I have the required skills now, but I was planning to get rank 4 for each of them. I did not however use concrete facts behind that decision – it just seemed like a good idea. After a Google search I found this useful Invention Chance calculator:
Inventing T2 modules has a 40% base chance of success. You need at least rank 1 in the appropriate encryption and datacore skills, so in reality you will have a 42% chance of success. A quick check at rank 4 shows the chance increases to 48.3%. That seems a worthwhile starting point.
If I was to spend 60 odd days to train up rank 5 in the three related skills, the chance of success would increase to 50.4%. That’s nice, but not really worth chasing after given this is just a casual effort. So I have about a fortnight of training before I will make my first invention attempt.
I have some 700 odd BPO in my library, so can source the majority of the BPC I might need myself. Very few however are duplicates, so if I wanted to get into this in any sort of volume I would need to buy extra BPO to generate copies from.
I have generated 20 max run Small Tractor Beam BPC already, and just kicked off a second job to create 20 more of them. That will be ready in a bit over a fortnight. I can see some forward planning and patience will be required when using public slots of this.
My initial reading suggests that T2 Module BPC will have 1 to 10 runs – depending on how many runs were on the T1 Module BPC used. I hope because I am using max run BPC that I will get 10 run copies upon a success. I guess it could also mean I have a chance of 1 to 10 run – where as if I used 50% max run BPC I might only have a chance of 1 to 5 runs. I guess I will find out soon.
I scourged the hodgepodge of stuff I have collected over the years, and found I already had 9 of the 12 invention data interfaces. Of course these were mostly just the cheap ones. For my experiment I was missing the Occult Ship Data Interface for the Amarr Assault Frigate. You only need one of these – they are spat out immediately upon the start of the invention attempt, and can be re-used. I didn’t bother doing much research, and just picking it up for 27M in Amarr. I already had an Occult Data Interface for the T2 Tractor Beam and the Esoteric Ship Data Interface for the Caldari Interceptor.
I need 1 High Energy Physics and 1 Laser Physics datacore for each invention attempt for the tractor beams. I had a few in stock, but basically just picked up enough in Amarr to try 50 invention attempts for each of the 3 items I am looking at. This cost 73M in Amarr on sell orders. I could have saved 10% if I waited around with Buy orders, but I wasn’t interested in spending the time. I split my purchases and cleared them out of the main Amarr station in two lots, to lessen the chance of being ganked.
There are plenty free at the moment, but I have noticed all being used up at other times. I’ll just have to put up with whatever situation I find when I am ready.
There are no named T1 versions of the three things I am looking to invent, so I don’t need to worry about those.
The Decryptors will be harder to work out if they are worth it or not. I suspect not for modules.
In Amarr, Small Tractor Beams are selling for 1M, T2 Small tractor beams for 2.3M. Given you will need a T1 version of the module to build the T2 that means very roughly you need to be able to invent and create the T2 module for under 1.3M. I haven’t looked at the manufacturing costs – but that is the starting figure I will be keeping in the back of my mind.
Assuming I read correctly, a max run BPC should mean each success will create a 10 run T2 BPC with ME -4 and PE of -4. Each attempt will cost around 450K in datacores. Assuming near on 50% success over time, the basic cost of each success will be 900K, or 90K ISK per module. If I get serious I can lower my datacore prices to buy prices, which would give roughly a 10% saving. Maybe more if I shopped around.
I have five decryptor choices for the Tractor Beam invention.
The Cicular Logic reduces the success chance by 0.6 and ME by -2, for an additional 9 runs. Or – given their current price, my rough calculations would be that it would increase the average invention cost per module from 90K to 820K, and drop ME to -6. That doesn’t make sense.
The Sacred Manifesto increases the maximum run by 2 and the ME by 1. Based on current costs, my rough calculation is that it would increase the average cost per module from 90K to 825K, and increase the ME to -3. Given I need to invent and manufacture within 1.3M, you would discount this one as well.
The Formation Layout, Classic Doctrine and War Strategon all increase the average invention cost per module to well past 1.3M, so it doesn’t matter what ME improvements they provide, I can’t make a profit using them with Tractor Beams.
I hope to get around a 50% success rate for my Invention attempts on T2 Small Tractor Beams, at an average cost of 90K per unit on a 10 run BPC. I won’t be using decryptors. I have all datacores required for 50 attempts, and just need to wait a couple weeks for skills to run down and the extra BPC to be generated.
Given the initial review on decryptors, they don’t seem worth using for module invention.
Total spend on this experiment so far – skill books and invention supplies, is around 152M ISK.
Next steps –keep a focus on the skills required for the T2 Frigate invention, while starting to look at the manufacturing process and costs. I assume I will have more skills to train, and probably more BPO to buy.
