Last ladder i played not the last that was but the one before that one.
I came up with my own build much similar to this one, but focuses a bit more on summons actually.
how i came up with this build, well i followed a normal nova psn necro build but it was squishy to say the least, ended up spending quiet some fg on a necro shield (30/20 5 psn nova 2 sockets and some minor adds)
just to reach max block but it was still kinda squishy take alot of damage from elemental crap due to low life for max block.
so i thought to myself well why not try with some summons as well and i tried around alot with gear and different skill set ups, and did a lot of funny stuff. maxing caster skellies with iron golem from infy was loads of fun in pvp untill you died and you realised you needed a new infy
The build i ended up with was this, maxing out psn nova, 1 point into lower resist and decrepify and all pre reqs ofcourse. 1 point into iron golem and golem mastery. 1 point into caster skeletons (cant remember what the skill is called) and then just points somewhat evenly in summon skeletons and skeleton mastery (added some more into summon than into mastery due to extra skellies.
gear:
diadem
2necro
20fcr
all ressis
amu:
2necro 20 fcr crap adds (llke 7 all res)
enigma
deaths web
spirit monarch 35fcr (our source of FHR and it also gives FCR)
TO gloves
arach
marrow walks (ofcourse the only option)
bk
10fcr ring with 11 all res and fire 24res and some minor adds.
MERC:
infy
rald andys
eth forty
iron golem from insight (just because shugging mana pots takes away alot of the fun from this build)
this leaves my character with
125fcr
55fhr
-60 EPR
around 20++ ish skellies
3k life and 75 all res. (yes high ammount life pb skillers)
i prefer +necro skills over pb since it gives to skellies as well
