Was looking to do Golems next, but there are 3 different golems for golem type in the data files? There's one Human and 2 AI, although for most golems one of the AI and the Human one are the same for most golems.
Also, the self attrition works how for golems now? They are not immune to repair so just as listed? (Last time I actually used a Golem was a long time ago.)
Basically the Golem loses health such that after the self attrition time, the Golem would have 0 HP left if it started at 100% and was not repaired during the time at all. However Golems also have a minimum of 1 hp, so they don't die because you forgot to turn them off and outside of repair, until a single AI ship hit thems. Even AI ships that have a 0 multiply versus the hull type, still do 1 damage to it an pop it. (As I discovered watching Dysons kill a AstroTrain, they take forever as they have a 0 multiplier versus it hull type, but those 1 do add up.)
Self attrition damage is also not like normal damage, so if you have a Mobile repair station/engineer/Fortress and assist large projects set high enough( I think you need that ), they will remain more or less topped off if you have the resources to spare.
As for the three types in the data files. You have the EXO wave Golems that attack, the Golumite AI and the Human Golems. I suggest that you use the Human Golems stats and make a section that notes how they are different for both of those, if they are, but I think the main difference is a lot less HP and that is about it.
EDIT: Forgot to make this clear, Human ones are not immune to repair, I don't know about the AI ones however as I have only seem them in EXO waves flying at me, and I am too busy trying to kill the group of 3 or 4 with there little Hunter Killer buddies to see if they are immune to repair or not.
