What to do?... What to do...

Hi guys!
Short story:
Was playing a Ethereal Knives Scion, was fun. Made a break, maybe a year ago. Now this little girl is on standard league with 100 skillpoint. Don't know what to do with her. Is Ethereal Knives with Arctic Armour and so on still good?
Would LOVE it if someone could post me an viable skilltree for her. Maybe a skilltree for Crit-Ethereal-Knives for the extra damage. Think my old tree was kind of HC build.
Took it from ZiggyD's guide back then.

Greetings!
