I'm interested in the different groupings mods have, particularly concerning how rare item mods spawn. I know the basic stuff- if a Savage mod is selected, no other mods from that group can be selected. However, I'm having trouble finding information dealing with the trickier areas. For example: If a +damage% mod is selected in the first slot, does that also mean that a Knight's mod (or something like it) could drop to compound the damage bonus? Or are these also part of the same group? Is there some information out there about mod groups? I've been looking but can't find anything. Surely somebody around here knows something. Thanks in advance.
