I'm lvling a grenadier assassin (FB as main attack) that is around lvl 50 atm. I noticed that with proper use of shadow warrior I could double my damage output, and I will never go back:Actually you can get a pretty hefty FB since effectively every "trap" synergizes it. On my pure trapper, its her secondary element at 4-5k dmg.
Yeah, with SM this is a pain. Much less with the warrior though, as you decide wht skills she uses. And using FB instead of the conventional traps also solves the problem of the 5 trap limit.While I've read you can get SM's with higher trap damage than your own, the time and effort it takes to get her to synergize is not really worth it, especially if she dies.
