Cardwise:
Red:
Velnia Monkey / Prison cutter with the respective purple cards is an easy 30% dmg when they proc the debuffs, but it’s rng based and needs purple cards.
Chapperition hasn’t got the ideal duration for damballa spam, but should be quite manageable to time with Gevurah.
Blue:
Nuaele/Zaura/Armaos as desired, same for every build tbh.
Green:
Pyrego, since int is your sole important stat. (zombie spr scaling isn’t bad, but you ought to be spamming damballa anyway.)
Gorkas only boosts the droprate of gear with random stats, but it can be quite nice esp for a good farming build like this.
Purple:
Biteregina/Rajapearl if you plan to use velnia monkey or prison cutters ofc.
You can grab gazing golems if you want as well, with maybe a dullahan to fill it up. But that’s not effective alas…
Marionette is somewhat promising, but can’t proc of zombie attacks and has a very low proc rate. (+ most enemies caught inside damballa will die anyway.)
Legendary:
Zaura/Nuaele/Rexipher or maybe a pantorex depending on what you want.
Use a primus rod, that’s by far your best dmg option and allows you to agro mobs at range due to the c3 kabba attribute.
