heres my build and gear for patch 1.11:
-all stats into vitality
-max teeth, max spear, max spirit, max wall, max prison, 1 point into armor, 1 point into clay golem, 1 point into golem mastery, 1 point into summon resist, 1 point into amplify damage, 1 point into iron maiden. This requires that you get to lv 96...so if yur not willing to do that...skip the summon resist, amp, IM, and mastery.
-gear: hoto/nec circlet/storm circlet/3pnb darkforce/bp nigma/arach/2 sojs/grim spurs/bloodfists/9x pnb gcs/anni/torch/10x 20 life scs
-nec vs nec gear: 35spirit sword/shako/storm circlet/35spirit/bp nigma/arach/2 sojs/bloodfists/9x pnb gcs/anni/torch/10x 20 life scs
some of the gear is a little expensive...but if you manage to get all of that and max the bone tree, your bone spear should to 5.4k-5.7k. with the nec vs nec gear, you should have the 152 FHR breakpoint and your bone spear should still be doing 5.1k-5.4k.
i use pnb lifers, so my nec has 3.3k life normally and 3.7k life for nec vs nec.
by putting points into clay golem, golem mastery, and summon resist, you can create a golem starting with 11k life. with a good cta, you can shoot its life up to 15k-20k. with one point into summon resist, your golem should be able to tank 5+ (i think?) fireballs, blizzards, bone spears, etc. the point into amplify damage is for team dueling, baaling, etc. the point into iron maiden is for killing barbs, chargers, zealers, and ww sins. combine with bonewall.
