Paying for help in optimizing my Icespear build

1) For your power charge builder use power charge on crit + faster casting + spell echo + ice spear. GMP isn't worthwhile since this spell isn't for damage, so to generate power charges quickly this is your best setup.

2) You should get a quality ice spear. You have no Q right now, which sucks for upgrading, but the difference between the projectile speed is huge. Try linking a faster projectiles and use a Karui ward to test out what faster projectiles are like. Big difference!

3) I'm a bit confused by your auras. Clarity and Herald of Ice with Eldritch battery? It seems that you should definitely find room for another aura. Anything is really fine, pick what you like.

4) I don't like your passive tree at all. You spend 4 points travelling in dex nodes just to pick up HP. This is not a great plan, even if you do get flask nodes. Here's an updated tree:

It gives you the same amount of life (minus flask stuff) for way less points, while also picking up more damage.

Some good nodes you missed:
I) Pierce nodes. Haven't played with them, but I think they're good. Might not be enough pierce to matter. Try them out.

II) Frost walker. Tons of damage and resist for two points.

III) The HP/mana nodes. These are way better than just straight mana.

IV) The witch starting node on the right. 40% regen for one point (and ES) is huge!

5) To figure out if you need crit multi or spell damage to boost your damage do the following. Add up all your modifiers to your ice spear (% cold damage, % spell damage) including passives and items. Then take that +x% to figure out how much damage spell damage gives you, and divide. Example, you have 100% increased damage. This means your spells do 1+1=2x their normal damage. If you get 20% spell damage, you do 1+1+.2=2.2x times damage. This means you deal 2.2/2 = 1.1x the damage you did before. Do something similarly for crit multiplier.

6) Get 30% movement speed boots. This will for sure improve your clear speed and safety.

7) You don't need more crit chance. With the +600% increased bonus you ahve 98% crit chance at max power charges.

8) Consider getting quality on gems, that will add a pretty decent (although not amazing) boost too for late game. Don't just GCP all of the ones you have though. Your gems will be level 20 soon so you can recipe (level 20 gem + gcp = 20q level 1 gem) for a big profit later. You could buy some quality supports in the meantime though.
