so you get this about 20% of the time your pet crits, and you get it for like 8 seconds, and all it does is make your ruin, bio 2 and miasma from 2.50 recast to 2.43 recast, it doesn't seem very useful for something that lasts for like 2-3 casts, and has a 20% chance of happening from a pet crit. Not sure if SCH get it too, but this needs to have a way better use.
