I've read in some of these postings that you cannot escape these cougars due to the fact that there is no zone nearby forcing you to root them and camp or sick your pet on them and camp....WRONG.
I arrived in iceclad soon after purchasing "Platinum Edition" to hunt snow cougars for the high quality pelt required for the cougarskin mask for my 39 ranger. These cats are not to be trifled with; never pull with any of their friends around or you will feel like your regular Christian in the Rome Colliseum. However if you do find yourself in the "I'm going to die soon" position, run to the end of the dock, hail the translocator at the end and type "north ro" and *poof* - you're safe! Practice this once or twice before finding yourself in the situation where you REALLY need it.
Sow in one form or another is mandatory in this zone - period. Many bad things roam this desolate zone and will group up on you quickly if you are running amok in terror trying to zone or get help.
Rangers: have your calm animal and panic animal spells on tap at all times and you will have little to fear. OH! Come in through Northern Ro Desert and save yourself a ton of running. This will also place you at the soulbinder and primo hunting ground in the Iceclad Ocean.
FYI: Snow cougars here are teeming and some conned light blue to my 39 ranger as well as dark blue. It's much safer and more fruitful than the Eastern Wastes for hunting these kitties! Good Luck!
