"PvP penalties will be applied always, unless both are from the same unit. So if you want to practice - make a Unit (group in other games) and hit each other for free
In MMO we plan to have only some area around starting city free of PvP and biggest part of the rest of the world will be FFA PvP. In LiF:YO PvP can be everywhere, unless server owner will enforce some rules on his server.
Well, crafting can be quite complicated
For instance to craft some sword you will need (aprox.):
Prospect for iron ore
Build a mine shaft towards iron ore node and mine it
build a furnace or bloomery to smelt it into ingots (you will need to chop down a lot of trees for fuel)
Chops some trees and use crapentry tools or workbench to create a handle
Go out in wilderness to find and tame wild cow (aurochs) and wild bull
Build up a stable and place them there.
keep them feeding with crops from your farm (farming is a whole another story
)
Once they have bred few times you can slaughter one of them in order to get a hide
Place a hide on a drying rack and wait for some time
place a dried hide into a tanning tub to produce leather after some time
combine leather, handle and iron ingots on a heated up forge (fuel again
to craft a sword or two"
cows and such is needed for leather . so you just need to level up procuration and animal lore then use the big traps for the cows and such.
