So I've been trying to decipher all the mechanisms used to make the engineer's support bot work, and there's one thing I can't find: where are the variables that govern the cooldown and range on the railman_support_aura affix?
Also, I did find out the formula for healing is the same as damage, except divided by 62.5 as opposed to 100 that is, (min/max)(graph value)(stat value)(stat percent)/62.5
Not sure if that's known already, but it wasn't noted anywhere so maybe someone'll find this helpful if they stumble upon it.
