There are faster, easier ways to "exploit" the game, than making extra toons and hopping worlds... using console commands. If you are going to go to all that trouble to bypass the portal restrictions, just "console it" lol..

OR

The way I prefer to play is, to not bother trying to ship my ore to some far-off place, but rather, build a mining outpost (complete with portal), and simply bring the smelter, forge and kiln TO the mine, process it there and craft it into the items I need (at which point they can be brought through the portal)

Not sure why people assume they HAVE to go through all this complicated, time-consuming process to take raw ores across the map, when they could just bring the work stations TO the ore, and process it right there.

It costs nothing to de-construct work stations.... you get all your materials back and can pass through portals.... They are portable,,, You can move them to wherever your next mine is, or next biome.

EDIT: I find it rather humorous that the OP marked the thread as "answered" by the guy who affirmed his cheating by saying "there is no cheating in Valheim"

It's still cheating, but what it should say is "cheating doesn't matter in Valheim"
