Skills Synergies

Please make more skills synergies, there are still small amount of skills which can be tied to get interesting results.
A lot of skills are not used, because they either have bad mechanic or can't be tied and used with others skills to benefit from that.

I.e. there should be more interactions between skills. This should bring more variability to the play style and allow to try different stuff, instead of leveling a new character, because of another ascendancy synergy.
