Soul Capacitor is a trinket that drops from Socrethar in Hellfire Citadel. This is a unique trinket because of the way it works. When it procs, you are actually doing no damage because it is being temporarily ‘stored’ for the duration of the proc. When it ends, your built up damage comes out of storage and is dealt in one massive hit with a multiplier. It can be great for high burst, singlet target and AOE damage.

However there are certain situations where you might not want it to go off (the proc to finish) e.g. running away from the boss due to an ability. Obviously while you are away from the boss you are not doing any damage – thus not putting any damage into ‘storage’, and if the proc ends when no enemies are around you will deal no damage. The best way to get around this is to use a /cancelaura macro. Activating this macro cancels the proc (called Spirit Shift) from the trinket causing it to deal how ever much damage was stored at the time. This will help you get the most out of your trinket.

Since I’ve earned my legendary ring, I’ve been having some threat issues, particularly on the pull with this trinket. Pre pot + Berserk & Incarnation + legendary ring + heroism, and then a trinket proc on top often leaves me dead from a boss one shot. Being able to cancel the proc early helps reduce some of these threat issues.
For some further reading about this trinket I’ll direct you to an article written by zoopercat from Ask Mr. Robot at Blizzard Watch. There is also a discussion threat for this trinket over at the Fluid Druid.
Hope you are feeling refreshed after our Cat Nap.
