So if I run both of these, do I stalk my Obsession 65% faster and everyone else 25% faster?
Good question, honestly. I'm not sure how the math applies here.
I think it is actually a multiplyer because most modifyers are applied that way. So it would be 1×1.25×1.4=1.75 (75% more speed) on the obsession and 1×1.25=1.25 (25% more speed) on every other survivor.
I could be wrong though. If anyone knows how it works, please tell me.
