"I also am Otherkin. Whenever autumn rolls around I can feel my kin-type slowly taking over my body. You must know, I identify as pumpkin. I can control it pretty good most of the time, but when September ends, I just cant hold it in anymore. Whenever Im outside I see my brothers and sisters being chopped into soup, coffee, donuts, cake, drinks, bread - ppl even cut human faces into their skin, making a mockery out of their noble appearance. When I see things like that I cant control my pumpkin urges anymore. My natural instincts kick in. I then sit down motionless, while getting bright orange." - Morgana L

Example:
I'm playing Galio and I use my ult, reducing incoming damage by 30%.
My defensive mastery tree is built up to the highest rank, giving me 4% reduced damage.
Because my killstealing skills are awesome, my leviathan has 20 stacks, reducing damage by 15%.
Our ever friendly allied Maokai uses his ult around me, adding 20% damage reduction.
Does this mean I have 69% damage reduction or do they stack differently? And if they do, in what order?
