i am trying to build a cabalist with bloody pox for main damage, i found several builds which i could use for endgame, i also got items available which fit. what i am looking for are tips how to level using bloody pox. i just killed krieg (veteran), trash mobs are no problem but bigger enemys are very hard right now, lvl 26 at the moment, any tips for me , should i max out the bloody pox path so i get enough damage at the moment?
pox doesnt’ stack on same target/recasting it over and over wont increase dmg, it just restarts it, that’s probably why you feel it’s harder on bigger enemies
What you want is a support skill that then either hits hard or does stack.
If you’re going Cabalist easy recommendation would be Ravenous Earth on the necro side.
Sigil of Consuption in Occultist stacks/multiple sigils cast under the same target will stack, so that can also be your support skill to Pox.
Good mix of Pox+Siphon Souls and ravenous earth or sigil should do it. It’s kinda a “trickle” affair, not exactly instant nuke dmg but it all adds up and RE or Sigil can rack up pretty decent with some choice items during levelling
*levelling item “spoilers”
ravenous earth MIs Grim Dawn Item Database
sigil MIs Grim Dawn Item Database
ok sigil sounds good, how much points should i invest in both knots?
max main node first, 1pt/low invest Destruction at first then max it later/specially when you get conversion items like the necro/occultist belt
Reason you might not have to rush max Destruction is you’ll also want some RR eventually, so slapping 10pts into Spectral Wrath(necro) and getting Vulnerability up will help your overall dmg too, climbing necro bar to unlock spectral etc ofc also helps with stats which will be handy during levelling.
And getting the sigil items basically adds a bunch of “carry” dmg too
*i’d get spectral Wrath before Vulnerability, simply because Wrath does dmg itself too, so like win win RR+dmg
should i use fevered rage in the beginning or add it later?
depends how brave you feel 
it will make enemies attack you a crapola ton more/faster, and can be generally noticeable on the incoming dmg front.
On softcore it might not really be a big issue outside non portal zones like skeleton key dungeons
Early game with maxed pox it can generally kill trash fast enough they wont be an issue, so you just need to be chonky enough to survive heroes/fatties, which can be doable if you max up res early and get a defensive skill or two like turtle/giant’s blood/ghoul (ghoul lifesteal wont apply to pox/sigil, it only applies to weapon attacks or skills/spells with %weapon dmg listed)
