Reduce 81 arti cooldown

[Encryptions]

30 seconds is a bit high. Can it be changed to 18 seconds?
A really helpful thing to add to proc cooldowns is have it show up as a green symbol for when your proc is active and red when it is inactive but on cooldown. Proc active for 10 seconds, green symbol has a 10s duration and after 10 seconds its got a 8s duration of the red symbol that appears. Total 18 seconds.
