Yes they stack. Also I did the math and it's worth having 2.

It says 20% chance to proc or 0.20. That means it doesn't proc 80% or 0.80.

Now let's look at the math if you stack two...

Both proc 0.2 x 0.2 = 0.04 or 4%

At least 1 proc 0.2 x 0.8 = 0.16 or 16% or 0.8 x 0.2 = 0.16 or 16% 32% of at least one since you add them

Neither proc 0.8 x 0.8 = 0.64 or 64%

Conclusion, 32% of the time you will proc at least 1 of the 600 armor buffs. There is a slight 4% chance you will get luck and both will proc giving you 1200 additional armor. The other 64% of the time nothing happens.

32% is extremely good, that's basically 1/3 of hits which is pretty common. Also keep in mind that the buff stays up for 20% so it's entire possible that it will trigger again before the 20s are up and become higher. I've tested this when you get have only 1 active, it starts a second buff with it's own 20s timer. So it prolongs the effect. Was hoping it would refresh the timer and stack both.
