ignite the the boar 2 times with the lighter and they'll explode. can be risky for your health but is worth a try for your kerfurO to get hash or servers safely.
or 2 hooks and any type of weapon (pickaxe recommended) hook them to front and back (could be annoying at times because they always face you) so they wont damage you all the time and damage them until they explode your hooks will always be in the middle trust me.
just don't use the molotov, is just a waste of resource since it requires 2 just to make them explode.
