[Build Help] PoE2 Bloodmage Spark / CoC – damage + proc issues
Hey all, looking for some help with my Bloodmage Spark / Cast on Crit setup.
I’m trying to start building and running my own Temples, but once I hit maps my build just isn’t coming online. Spark damage feels really low, and my CoC barely procs, so mapping feels bad and bosses are a slog. Most of my currency so far has been from leeching Temples off other players, but I want to start doing my own instead of relying on others.
What I’m confused about is how other Bloodmages are getting:
- 100k+ Spark damage
- Consistent CoC procs
- What looks like 2–3 Comets per second
Clearly I’m missing something fundamental. I’m guessing it’s one (or more) of:
- Crit chance is at 100% with pinpoint critical (67% without).
Questions:
- What should I prioritize first to make CoC feel consistent?
- How are people actually scaling Spark damage to those numbers?
- Is it worth pivoting into Elemental Weakness with Doedre’s Undoing, or is that bait for this setup?
Any advice, explanations, or PoB links would be massively appreciated. Thanks!
