Tremor support gem is bugged.

The chances of an aftershock proc are weird.
This doesnt seem to be an impression only, bc the reddit user "Emu_XD" tested 100 times with the follow result:

Total slams: 100
Total aftershocks (AS): 92
--
No AS: 69 // One AS: 17 // Two AS: 0 // Three AS: 3 // Four AS: 0 // Five AS: 0 // Six AS: 11


Others users reported that:
- if the 30% AS chance proc, then all of your AS from other source would also proc
- if the 15% AS chance proc, then the 30% AS chance would also proc and all of your AS from other source
- If the 10% AS chance proc, then the 30% AS chance and 15% AS chance would also proc and all of your AS from other source

However some of these procs occurs simultaneously, therefore the user Emu_XD spreadsheet should not be correct, bc you cant visualy see 2 AS occuring at the same time. To reproduce this you should use a poison stack from some source. You can see it giving 2 stacks of poison with that looks like one AS.
