A level VIII boar can easily make short work of you and will destroy leather armour faster then you can hurt it, hell it can 1 hit ko a player with 30UA but no armour.
Too keep the boars from spawning on your front door build a fence around your house and other buildings, and place a personal claim covering that entire area.
As others have mentioned slings from behind a fence are the best boar killers for those without decent combat stats, just keep a renewable source of stones within easy reach of you where the boar can't get to. as for the marksmanship level, if you are willing to wait 5 mins between shots and then only have a 45% chance of hitting then a skill below 9 is ok if you want to fire more often with a greater chance of hitting aim for a skill level of 15-20.
The 4400 LP needed to go from 1 to 9 marksmanship is not to bad as compared upgrading UA from 15 to 60 UA (168750lp) which is what is the recommended UA needed to fight a boar (according to
viewtopic.php?f=2&t=6518).
Save our trees. Say NO to clear-cutting.
