While working on my "Frankenslots" for my scrapper I decided to check and see what I should put where and what slots will give me which boosts. After going over the whole list I think I've found ALL of the ones that will give good enhancements. I've even marked which ones can be slotted into passive powers (heal/endurance/etc) and which ones can go into toggles, which would basically make these go on forever. There are still a few that are single shot, but if you use it often enough, it's worth it.
The best perk of these is that L10 or L50, they always give the same bonus.
