I grouped AAR and Obliteration into one point because they are similar but these are separate builds.
You can convert those skills to Cold.
First I think you should decide on a build / class, what skills do you like to play and then we can help you out with that and think how to level it etc.
Some asked how to level to this Cold build [1.1.9.1] King Trozan: 4:24 Crucible Gladiator 150-170, Shard 100, All Celestials cold caster Druid by mad_lee [vid][g4][everything+]
And I answered
“Develop Trozan / Arcanist, farm items somewhat as in the following guide and use Wind Devils / Storm Totems as additional DPS / devotion proccers. But follow devotions from the OP.
[1.1.8.1][Guide] Trozan's Ice Shard - A cold Warlock Beginner Guide”

Maybe you play this since there’s is a beginner guide for TSS Warlock which you could follow and learn a lot from ?
You just play Druid instead of Warlock but it’s very similar (because for both build Arcanist is the main class and Occultist / Shaman are support). Druid might be even easier because you have more Cold / Lightning spells (Devils / Storm Totems) to choose from so there’s far less need to improvise at early levels (for example by using component skill / Olexra as in the beginner Warlock guide)
Should be beginner friendly because you can kite / stutter step everything with cooldown spells to death and Energy management is easier.

Actuallly I made it for hybrid Cold / Lightning Warlock
which reminded me that I chose it over Druid because
Trozan set gives Occultist beautiful blue Sigils:
