Blaze Artillery on the arsenal UI shows a base duration of 3 seconds (when the ability is at max rank), I found this bug when I was messing with different builds
With 203% duration, the ability shows a duration of 6s (screenshot 1)
With 200% duration, the ability shows a duration of 5.67s (screenshot 2)
With 227% duration, the ability shows a duration of 6.67s (screenshot 3)
With 176% duration, the ability shows a duration of 5s (screenshot 4)
The math doesn't add up,
3 x 2.03 = 6.09s (not 6s)
3 x 2 = 6s (not 5.67s)
3 x 2.27 = 6.81s (not 6.67s)
3 x 1.76 = 5.28s (not 5s)
