people have made spearazons on d2pk, they are entertaining, but have sever limiations. Some opponents like winddruids just stomp them really bad and there is nothing they can do. And the no block or hp means opponents like barbs can pk them really fast.
It's not really a difficult build to play, just very fragile, and can get killed by evadelock like any other zon. The way players have built spearzons is to take advantage of d2pk's rare import weapons and use 450ed/+ rare eth spears, with an all str zon build. enigma with a bit of fcr, and go telestomping people in pub games to wtfpwn them with some rediculous damage. If they hit they kill, if they dont they are very fragile and get killed fast. Entertaining build, not too difficult to play from a gameplay perspective just.. very fragile and a limited build because of this.
