+ Buffs for you and your lane mate.
+ Good durability
+ Good cooldown
+ Awesome controle
+ Good for save you and mates.

As you can see it's not DD spec =)
It's pretty good to initiate battle, helping catch enemy or saving some ally ***es.

I'm currently use #3 because I fin that you can't have more 110 hp5 and I change "Silverfox Girdle" to "
Frostbound Hammer". it's really good help to control enemy.

This priority sequence of skills need good teammate who can do fast tons of damage like Bakasura, He Bo, Ao Kuang, Basted etc.

You should use "Hand of god" as fast it cooldown to take buffs for you or your DD (I prefer HP regen at first 10 sec). Also you can use it to break basted ult (And I really love it).

Combat skills:

Frost Breath on as much enemies as you can -> 1-2 hits -> Glacial Strike + Ice Wall to stop enemy again.
Use Shards of Ice only if you know that enemy can't run from you (Dash and jumping skills or he\she far away from you).

Also Frost Breath and Ice Wall is two great skills for save. Especially in jungle.
By using wall you can stop many control skills like Sobek's dash Ares's hook etc.

You know no any supports can't do anything without team.
You shold every time know that your team can and ready to help you rush. Don't afraid die in combat if you can help with good bunch of kills.
Also besides your skills for controlling you have a real dat frozen ***, which you can use for block enemy (Really helps much times).

Know your enemies and allies. Do not die in vain but don't be afraid die for triple/quadro/penta kill ;D
Most time use your skills in help to teammates and don't block they by your wall ;)
Enemies... Try to catch them all by your Frost Breath.
And do not forget about Frostbite, it's helps for stealing frags, yay!
