Assassin/Ninja Help Assassin Thunder Build

i'm a lvl 37 assassin player, i know it's maybe a bit early for me to think of build for my gameplay, but i still want a thunder build for my level and hope that i can get some advice on further direction of future level thunder assassin build.

 

way too early as you change gear every 5 lvls or so at your level. You dont usually need a proper build until lvl 80+

 

Do several sand swept tomb runs to get hashr’s claw(level 39), for armor just get the armor with most hp and doesn’t have -melee or -thunder dmg

 

for the armor part do i have to focus on special identifications like + dex, + thunder dam etc? Also is it important to obtain full legendary armor or the rarity doesnt matter?

________________________________

one more question : should i add high tier powder into hashr claw?

 

I use two t5 thunder on hashr claw. It works great for me, and I use it rn, a lvl 60 assassin.
