I have been working on +skills +life GCs. But what SCs benefit a cold sorc and what should I be searching for? I have skillers and also a sunder coming from my ladder characters, I am just lost on which SC to go for...

89 Orb sorc

Also, I run a FB/Orb now, because of the lack of a sunder, but this is about to change.

I dumped most everything into vitality, not energy, so with CTA I am at 1k mana with an insight merc, mana is not an issue unless I am hammer by a mob, due to energy shield.

I have energy shield currently, just 1 point.

When I get the sunder I plan to respec to full cold, Is it worth it to keep energy shield? Should I still run my vitality as my main stat? I am hitting 1.2k Orb damage currently without maxing synergies and only did like 13 base cold mastery, should I be aiming to max cold mastery after the reset as well, since the change with sunder? Is it not like 1/5th as effective now after a target is sundered?

TYIA, trying to streamline my build.

I have all the gear I want and need for cold, just trying to perfect the build and charms.

PVP I don't know
PVM your gear is plenty good play what's fun

I would do Orb blizzard if you like orb. Drop the ES and go vita block

this will work with players 1-2

If it's players 8 then switch into pure blizzard.

SCS don't matter. What are you going to get FHR, LIFE or Resists? Doesn't matter for PVM when you have the gear you have.
