Can an enchanter with Collaboration wander in Kael without being attacked ?

Sort of. As far as I know, there are three factions in Kael - the frost giants, the storm giants, and King Tormax. I was able to get to dubious with either the frost giants or storm giants when I first set foot on Velious, but couldn't get non-KOS with mobs on King Tormax faction. However, you can only have Collaboration active on one faction at a time, so if you're in an area with both storm giants and frost giants (for example, near the bank) you won't be able to get non-KOS with both. Having said all that, you can just invis and run safely from the EW to WL zonelines regardless of faction.
