What should I sold my gskull with?

2*15ias jewel w/ 40ed
Or
2*15ias jewel w/ 15max dmg

Nothing

Swap to 30frw 3 socket circ or mavinas circlet with 40/15s or xx/15s to budget

Dracs to LoH and ring to any other

15ias 40ed or 15ias 15max depends on the specifics of your build, like what's your inventory, are you full glasscanon etc

Well the Mb faith only requires 45 ias to hit Max fps... So I hit that without a 45/120 helm with cats eye and gskull 2os and I can do Baal runs with burning souls due to dracs and strafe.... For some reason strafe and life tap is so important against burning souls...
I seriously do really well against burning souls and die maybe 1/100 runs due to me not paying attention cuz I also am a hybrid Java

Skills maxed
Strafe
Magic arrow
C's
Light Fury

Taurean approves

Even with a plain 3x 15ias jewel'd helm, lilith0's build would be 10x better. Hell even without hitting the ias bp

Just wondering why cuz I have 2 x 9min dmg dual leech rings with resist I just think that survival tumps an extra 200 dmg with a slower bow... But I do believe if u go full strafe than maybe the gmb or diamond bow would be worth it.

But my question still has not been answered what should I sok my gskull with Ed or pure dmg
15ias 40ed Jew *2
Or
15ias 15max dmg Jew *2

if A is your base dmg
40ed gives 0.4*A dmg
for example 200*0.4=80

if B is your total ed
15max gives 15/2*(1+B/100) dmg
for example 15/2*(1+900/100)=75

If using a low dmg bow use 15/15s because 80% of fuck all is still fuck all. Otherwise the suggestions in your thread so far are accurate.
