My friend found a lvl 12 gun on his summoner that gave summon warper(lvl 20) + spectral strike (lvl 25)

just aug'd +2 napalm strike (level 30 engi skill) on my item level 13 (requires character level 8) arclight rifle
aug'd when i was level 7
dropped from shulgoth at level 5

its a low lvl MM skill (lvl 5)

I am curious about high lvl skills for the whole faction (like the one I posted) at very low levels. uniques break the rules so nn those.
named legendaries (like the spectral lash focus/ reach of the fiend) break them as well.

I am trying to fiure out what goes into getting said skills on the items. My idea so far is possibly the new character classes have these skills at lower levels. Otherwise it is usually slvl - 9 = clvl

today( 2 minutes ago) weapon character lvl 7 dropped with napalmstrike +1 ( lvl 30 skill). without aug'ing. ;x
