You can just run there with a stalker, trigger the mine, blink out. You dodge the damage.


True. However, if you find yourself in a situation where you are retreating across a line of mines (don't ask me why), then maybe a stalker blink train is faster. The effective radius of the mines should be about 5 - (2.9531)(1.5) = 0.57.


I'm not sure why you used stalker base speed to calculate the speed of a blink train, but nonetheless...

Show nested quote +

d = sqrt(25-(C/2)^2)


sqrt(25-(C/2)^2) != sqrt(25) - sqrt((C/2)^2) ; and you forgot the power of two.

sqrt(25-(2.9531/2)^2) = 4.77.

tl;dr Stalkers are not faster than speedlings.


I was looking at how far the stalker can move towards the mine before blinking. Of course, since the blink distance = 8 and
8 + (2.9531)(1.5) = 12.4, we see that the stalker doesn't have to blink entirely out of the mine's radius. It can walk in a little, blink almost across, and then walk out.

Everything is considered in the worst case scenario of traversing the diameter of the circle. There is no need for Pythagoras.

Also, on another note, what happens if a dropship picks up the first unit to enter the mine's radius while that unit is inside the radius? Would the mine find a new target since the unit isn't on the "game board" while its in the dropship? Could you theoretically (although probably not practical) use this to get slower units to move safely across if you hit the mine at a certain angle?

Edit: Could you also do some kind of trick with burrow?

doesnt this pretty much only apply to units that walk in a straight line?

Is the math for entertainment purposes? Seriously a lot more knowledge than necessary for comprehension of the topic.

That is math's explanation for: "If you run quickly enough when you triggered the mine, you won't be hit.

(Mine's radius minus Effective Radius) divided 2 = the distance your unit can step in and back out of radius w/o being hit (ofc depending on unit's speed, too slow units still will be hit).

Did anyone try whether you can use the hold-Lurker trick to make Widow Mines hold fire? ;p

I was wondering. If I a unit enters mine range and just sits there, by spamming stop key command can I stop it from triggering?

This is an excellent mechanics post that can be used to combat mines. I hope blizzard holds back on the nurf stick until we can work out countering mines a bit more.

Hi, Lone

I am mutalingyu. I am a SC player from Taiwan. After reading your article, I would like to share this article to my friends on the SC forum. May I TRANSLATE this article into Traditional Chinese version?

If there is anything about copyright or something I need to do, just tell me and I will do it.

I've seen Stephano do this on his stream. Basically, when you burrow a unit that is targeted by a mine, the mine will still fire at the location of the burrowed unit, but the latter will only take the splash damage, and not the single target damage.

I don't know if this also happens with drop micro.

You deserve a lot of praise for this cool post. I wonder if this delay time will figure in future balance decisions.

I get the OP. What still I don't get is why units that outrange the widow mine (ex. Stalkers) still trigger them sometimes even they are at optimal distance from the mine.

The stalkers' 6 range is calculated from the center of the unit, not the edge. So part of the stalker sometimes extends just into the mine's range. That's why pros tend to move their stalkers back after each volley on mine(s).
