EGO Level and Weapon Mod Slots
So I think I've figured out the level triggers for the number of mod slots on weapons we encounter. This is based purely on my own experience, what I've heard from others here, and deductions I've made therefrom. It could be totally inaccurate. If anyone can confirm or refute these I would appreciate it. Basically here is how it seems to work:
EGO Rating 1600 - 2399: weapons have 1 slot
EGO Rating 2400 - 3199: weapons have 2 slots
EGO Rating 3200 - 3999: weapons have 3 slots
EGO Rating 4000 - 5000: weapons have all 4 slots
Basically, at level 1600 we start getting the higher level weapons with more and better bonuses. Weapons we encounter will have only 1 or zero mod slots open. An additional slot will open up in intervals of 800 EGO levels.
Below is pure speculation on my part. I do not remember how it was before level 1600. However, this follows compatible logic to the above. Anyone who actually paid attention at that time and remembers, or who is currently playing a low level character, please confirm or refute:
EGO Rating 0 - 399: 1 slot
EGO Rating 400 - 799: 2 slots
EGO Rating 800 - 1199: 3 slots
EGO Rating 1200 - 1599: all 4 slots
