Assassin/Ninja Help Attemp At Thunder Build, Need Advice

https://wynndata.tk/s/4hDtLC

So I made an attempt at an assassin thunder build, where the main goal is to spam as many spells as possible while mostly dodging all attacks. This is my first time making a build and I have no idea what I'm doing. If anyone has any advice on how to improve this build, it will be much appreciated!!

 

hive dagger/thrunda ripsaw/lightning edge gives more damage

also, i suggest using atlas because it'd be hard to proc your mana/lifesteal with such high attack speed, and atlas also buffs ls/hp/mana steal

as for the other problems, too lazy to type rn rip

 

Ok, lemme try to improve:
1. As @by2011 said, hive dagger or thrunda ripsaw works better (i'd recommend hive dagger)
2. you have horrible earth and wir defenses, you should use less items with negative earth and air defense and more items with positive's
3. why concentracion? You should build mana regen OR mana steal, and for mana regen moon pool works better
4. use atlas for more mana steal and low attack speed
https://wynndata.tk/s/9iFIbV probably still not optimal, but better

 

imo some mr is really good to have even with a ms-based spell build since it helps out whenever youre not within reach of hits to steal mana off of (like when you get push-spelled or are out-of-combat) and youre not completely helpless if your ms ends up not triggering for a couple hits

anyway heres mine

 

Well, you still have natural mana regen.
Cool build, made something similar aswell but didn't want to revamp the entire build.
