+405 to power for 20 seconds = best in slot for a Watchman.
I have an augmented Rakata one which adds +380 and has a +89 endurance and +18 power on it so I'm using that right now. As soon as I crit on my Campaign one, I will put an augment into it and it will replace my Rakata relic. My 2nd relic is the one from KP HM that does the +224 damage proc (IIRC, could be off a little on that number). As soon as I get my 2nd set of 200 daily comms, I will get the Campaign version of it (haven't decided whether I'm going to risk another R/E on a 200 daily comm item, lol) and my relic slots will be complete till 1.3.
