So you voted the build is bad cause you prefer something else over another ?

Well me and Sov did some testing with low lvl bs damage using low lvl lower resist and amp.

with lvl 5 Lower Resist here are the result of 5 bs.
17
19

with amp.
17

18

then i highered the damage of bs and tested again.

Lower Resist.

65

Amp

I know this testing is short. But it does give the info we need.
It is clear to me that Lower resist would end up doing more damage at higher level since it become stronger unlike amp.

There is also that you put a point in Decrepify to get Lower Resist. Decrepify will slow targets speed, damage and physical Resistance -50%.(perfect to Bone Prison someone) There is also iron maiden that can be useful in some situation and terror for leveling.
