Rate and help my lightning tendril witch!

Hello. This witch is currently level 79. At level 80 I will take Assassination.

I have 5.2k ES with a 3 dragon helm, 6k with a proper ES hat so don't think I need more ES, but I would like to pick up mind barrier over the nodes begin CI. Also I used to have the witch mana & mana regen nodes, but swapped them to the templar mana and life regen nodes which gave me a slight more mana regen overall, plus more life regen for zealots oath. I could pick up those mana and mana regen nodes again maybe because atm I can only power a 4L lightning tendrils or storm call, and will eventually want 5-6 link.

I mainly use tendrils / life leech / power charge on crit / spell echo for mobs, and swap tendrils to storm call for harder encounters that I cant be close to.

I get enough str from the several +10 nodes in the templar area plus equips, and the only dex gem I use is a level 8 AA atm, plus optionally lightning trap, but I have enough geared dex for that at level 18.

I like the originality with Artic armor and CI but its
kinda hard to rate. Personnaly I would go with more ES instead of AA.

I can say that you should take the nodes behind CI as fast as possible.
also the 3 faster shield recharge nodes near Ci are not really worth it.

also, i dont know if you run the unique Eye of Chayula but you could consider Pratical Application to avoid getting stunned since CI gets stun easily.

If you want to drop AA, you can invest in aura reduction instead of mana regen and run purity of lightning or something (heralds...) to counter lightning reflect.
