You should at least pick 1 element... most ppl have 2 but don't get more than 2...
imbue is pretty much required you can do without it... but the extra damage is really nice I mean REALLY.
most ppl suggest getting soul spear and the pedal spear.... others are more of a preference thing...
I'd suggest putting 1 point in each skill try it out... and if u don't like it or don't use it you can always get rid of it with the lvl 20 quest. its not like theres a max number of sp u can get so no point being stingy
