Can someone explain "movement speed factor"s?

Like for those poison abilities, where you can slow down enemies and their attack rate.

How exactly do you determine the percentage? Say I want it to slow down enemies by 20% on lv1, 40% on lv2, and 60% on lv3. Do I fill it in as:

1.
-0.20
-0.40
-0.60

2.
0.20
0.40
0.60
or

3.
-20
-40
-60

And how about the attack speed factor? Thanks a lot.

well there are severals ways to affect movement speed. And which one you use largely depends on the ability. Your third option would only be used if you were directly decreasing movement speed (which btw ranges from a move speed of 0-522).

for slow poison I believe it would be the second option, but check the default settings first to see whether it is positive or negative.

EDIT: sorry i forgot there are times when you use full numbers. Blizzard was kind of lazy and inconsistent on the abilities. I suggest simply checking the default settings to figure out which one to use.

ps. nice submission.

You can use Blizzard's original abilities as reference. Look up Poison Arrows, Frost Arrows, Thunder Clap, etc. What Mystic Prophet wrote may be right; They do have a tendency to not stay consistant with how ability fields are done. :/

Indeed, I tried filling the field in 3 different ways each level just to try it out, but none of them seem to be slowing my target down. WTF hahaha... The poison works, but the slow down doesn't.

Maybe I should input higher, exaggerated numbers to test it again first.

Thanks guys.

Also, don't forget that if they have any speed buffs those tend to interact with the attack speed bonus from agility. I always found it kind of frustrating that an 80% slow would leave a low level hero decimated, but one with a high agility (due to the attack speed cap of 400%) wouldn't be phased at all, since his attack speed percentage was still above 400%.

would have been nice if the spells effected total speed instead of only the base speed.

Set the abilities to their default. that will let you know which one to use.

ps. hi again ignited.

Ah but see I was using it to attack a creep. And this creep just waltzed away from me "la la la" like nothing is going on. It should be in a Purged like state hahaha.

I haven't re experimented yet due to college stuff, but I'll post the results here when I have. Thanks again.

then I'm guessing you used a .0x decimal in an ability field that requires full numbers?

the only way to know for sure is to set it to default. if the field has 20 listed then use full numbers if it has .20 then use decimals.

and unless you're using an ability that normally speeds units up (like endurance aura) you shouldn't ever need a negative sign.

Well the base is the Poison Attack ability, and the default is, unfortunately, 0.

But I'm back to editing now and I will post what I found.

Blizzard movement speed factors work like this:
movement speed X factor
so if speed is 100, and the factor is 0.6 (as with slow)
100X(0.6)= 60 or 60% of original

if it says movment reduction then its
Movement speed X 1-factor
100X(1-0.6)= 40 or 40%

if it says movement increase its
Movement speed X 1+factor
100X(1+0.6)= 160 or 160%

In slow aura u will find the momvent speed factor to be -0.6 (basicly movement increase)
Movment speed X 1+factor
100X(1+-0.6)= 40 or 40%

so Poison says movment speed factor, therefore it is the absolute multiplier
basicly look wat blizzard already wrote
Understand?

(btw neither 1,2, nor 3 that u wrote were correct it should be 0.8, 0.6, 0.4)
