Well, my method was to always have a portal nearby (never leave the base without a portal materials and a new portal back at base), and when I died, I wasn't more than a hundred meters away from my bed.

I just stuffed myself with my best stamina food, tried to go as near to my gravestone as possible without using any of that stamina, and just made a run for it butt-naked.
The only problem was when I had the strength belt and more than 300kg in my inventory, as I then had to pick up the belt, equip it, run a circle to lead away the mobs, then run back and pick up the rest of the gear on the second lap.
It worked in Swamp and Plains, Mountain needed a stack of freezing resistance mead at home.
I recovered my stuff alone from Bonemass and Moder this way too.

If you don't stop moving, enemies have a really hard time killing you in this game. Most melee mobs can't actually hit a jogging player, and with no hitscan enemies, all ranged mobs' projectiles can be dodged easily too.
