Finding the sites 

 Winter Nexus combat sites spawn in systems affected by volatile ice storms in HS , LS and NS . LS sites are assumed to be the most valuable ones, followed by NS and then HS . 

 Access and difficulty 

 HS sites disallow Marauders unless a Cryostorm Clarifier (from Yoiul LADs ) has been deposited into Sansha's Transit Modulator, upgrading the site (increased difficulty & better loot) 

 LS sites can be upgraded with a Cryostorm Reconciler 

 NS sites can be upgraded with a Cryostorm Mapper
