Assassin/Ninja Build For Somewhat Decent Assassin

Hey just wondering if there are any builds I can do for Level 35 Assassin and also I've just been putting points in strength and dex and was wondering if that's the right move?

Main attack damage but harder to obtain

invest skill points into what you need for gear then intelligence until you hit the highest threshold here https://www.wynndata.tk/mana/ if you aren’t using a spell build or have hit the highest threshold the put the rest of your points into defence or agility
