Need help with skills for GLAVIE

[Sam of Honor]

Which series from Cold and Lightning are good for Glavie users?

I know which series are good from Fire, but I don't know which ones are good from Cold and Lightning.

Thanks.

Now, i'm assuming youre a pure-str glaive user.

Not sure if you wanted to take both trees, but i'll just list which ones are good from both.

Cold:

Frost guard series - Max it, great phys. def buff
Frost nova series - Max it or leave them at level 1, good for freezing mobs/players, book2 has a great AoE bonus
Cold armour - (passive) Max it, great phys. def bonus

Lightning:

Piercing force series - Optional, increases your max damage by around 100~250 depending on your level.
Grass walk series - Max it. Increases moving speed which is practically required, book2 has a great teleport like move that is great for catching up to people or a small speed boost.
Concentration series - Optional, increases you parry ratio, which reduces damage directed at you. Very nice skill.
Passive - (forgot the real name, it's the bottom skill) Max it. See Concentration series.
