Simple question of do two spells that both increase movement speed stack?
Example: Would Battle Rage (+25%) and Rush (25%) creat a +50% increase in movement speed?
Battle Rage and Rush would not work together because they are both stances, and stances cancel eachother out if you try to stack them.
I could've sworn though that I have had Sprint (Warrior stance) and Windborne Speed (Elementalist enchantment) up at the same time, but I don't think the speeds were added. I assume you just get the speed boost from the higher one.
I'm pretty sure speed buffs do stack, to a cap of 50% increased speed. Stances can't be stacked, since you can only have one stance on at a time, but I'll have to try out a combo using non-stance movement buffs to see how it works.
a couple BWE ago I stacked sprint(25%) with wind born speed(33%) for a nice boost but then in a more recent BWE i tried to use sprint with illusion of haste(33%) and didn't notice a speed boost. So basicly despite testing on this subject im confused mabye some dont stack or they changed it between the two BWE.
I did not however go back and test windborn speed again :/
