assasinbuild: Lots of agi. just get enough str for the crossbow you want to use and armour. lots of athletics and weaponsmaster. wpf in crossbow. Get Some camoflagearmour, white for snow, greenbrown for forrest and so on. get 2 1slot crossbows + bolts.
Bring no meleeweapon, as it is futile to engage melee without a proper weapon,ps,armour.
Then sneak up on someone unaware, shoot them at close range in the back or head with crossbow. This will stun them abit, giving you the chance to switch weapon and finish them with a 2nd shot if they are still alive. the 2nd crossbow will surprise most players thinking you are reloading or switching to melee.
If things does not work out the way you planned, you can outrun most players, hide and reload.
Crossbows are a dirty,cowardly and OP weapon.. maybe abit boring, but very effective.
And if your aim is to be an assasin, you go for the most effective.
Tip your hat to the crossbowbalanceteam.
