What Build should a Shadestepper use and how to get ability points

The tittle pretty much says it all.

 

Idk about a build, but ability points are from leveling up just like skill points. You get one ability point every few levels, and you can see when the next one is by hovering over the orb that takes you to the reset ability tree section in the ability tree (or just by reading the level up message which says how many levels left)

 

ability shards u should get doing dailys/weeks quests, and also u can buy it on market (pretty salty rn, ~8EB)
about the builds, probably a heavy melee build, i can show my build for example
