Underneath is my current skill tree at lvl 80 with all skill quests done. I'm not really sure where to spend the rest of my points.

Are Shiver or Chilling Armour worth spending one point or Frozen Armour is more than enough?

Should I go for:
- Maxing Glacial Spike to further boost my Blizzard?
- Maxing Fireball or Lightning for inmunes?
- Frozen Orb, or is just 1 point enough to clear rooms quickly?

1 point frozen armor.
Max all synergies for blizzard. Fire or light points will not help you. Use merc eth insight for cold immuns

Cold mastery until -100 to -150/-175, depends on preference.
Mobs cannot have less than -100 res, so maxing cm is not worth it.
1 tele
1 warmth
1 static
Max blizz+synergies
You can go 1pt shiver armor.

Getting a 2nd element on such a deep blizz build is not worth it, imo.

Best merc option is eth reapers, btw.

glacial spike

Not a single point in FO is worth? For easing room clearing.

Blitz + Glacial/blast does the same

It'll only help you in normal and early nm.
Max Glacial spike and use it to clear. It's just as fast as FO.
Dont waste points in other elementals. Not going to do shit on hell.

Online - 1 point frozen orb (for rushing/helping others in normal)

max glacial spike

Only for rushing purposes.
