How to scale the damage of Bane

Example: I have eldritch knowledge with 30% chaos damage increase but is it better as a 14% spell damage + 4% non ail multi jewel?

This entirely depends on your character. I'll give you some more or less realistic examples comparing 16% incr. spell damage to 4% non-ail multi (which is the effective difference between your two options):



Char A has 300% incr. chaos damage and 0% non-ailment chaos damage over time multiplier.
Adding the additional 16% incr. chaos damage from eldritch battery will result in 4% "more" damage. Adding 4% NaCDoT results in 4% "more" damage. Jewel and Eldritch Battery have the exact same effect on Char A.

Char B has 100% incr. chaos damage and 100% NaCDoT.
Adding 16% incr. chaos damage will result in 8% "more" damage. Adding 4% NaCDoT results in 2% "more" damage. Eldritch Battery is superior for Char B since he has high NaCDoT and low "total increased damage".

Char C has something that makes the jewel superior ;)



tl;dr:
Compare for your char in PoB to be sure.
In general: A lot of "increased" has diminishing returns. NaCDoT is usually great, but has some diminishing returns. Pure "more"-modifier (e.g. squeezing Zealotry Aura in) have no diminishing returns.
Prioritize "increased damage" if total increased damage is low. Prioritize NaCDoT if NaCDoT is low. Always grab every "more"-multiplier you can get.

I like using the temp chains version with wither totems, the double curse is still going to kill all the trash in 1 hit and then drop the totems for absurd damage stacking on anything tankier.

Another option is Blight on totems with a Spreading Rot jewel, which puts Wither on your Blight and extends the duration of Blight's hinder. Then go with Enfeeble over Temp Chains with Despair in the Bane link.
