1 thing is a miss,dunno maybe due versions..
When I had TerrorBlade I bought skadi and S&y. Skadi was meelee and I had skadi effect. Same is when I used metamorphosis to become range hero-I had only skadi effect..but when i had ranged skadi and was meelee hero I had maim only
Looks like meelee skadi has the highest priority(or ha increadibly strange bad luck with maim)
