Great suggestions everyone. Thanks.

I've got a ridiculous amount of stockpiled supplies, so I think I'm going to try to gear up enough to build a staging ground, and then from there see if I can just keep charging in with eikthyr power until one of my bodies makes it close enough for a supermarket-sweep on my original corpse.

If that doesn't work, I'll try to terraform my way there so that at least I have some protection from that ice-shards shotgun Moder keeps hitting me with every time I get snagged on scenery or a wolf. I figure the ice-shards will be blocked by terrain even though the frost-breath appears not to be.
