I have a question regardeing newly learned Bot shells aswell... it seems to me that Nhime mostly creates generation 1 and 2 shells... I made her learn with generation 2 Shells... does the original bot shell have an impact on how good Nhime can craft them afterwards or am I simply unlucky?
I actually thought about it so the distribution is indeed tier dependent:
You can see that e.g. for simple tier it is 50% basic, 33% advanced, 16.5% military and 0% elite with gen sampled from [1,1,1,2,2,3].
The highest tier has 20% elite, 80% mil with gen sampled from[2,2,3].
TLDR: It gets better with higher tiers but gen 3 are possible for all.
