Advice for PoE2 HC SSF Campaign Challenge

fulmi conc+ voltaic mark for clear, grab a +1 quiver and +1 bow and keep gambling bows till lvl 41, when u gamble quivers for a +2

swap to pconc at lvl 61 or so

Lightning arrow/rods builds are pretty nice early game when you don't have much in stash.

I like to level multiple characters at once, I'm typically a bit more careful about my fastest farming character. I try extra hard to keep them alive so they can quickly get drops for my other characters.

Biggest mistake is getting too confident and dying lol.

Second biggest mistake is letting my stash get too ridiculously unorganized.

Infernalist minions (extremely boring, and minion AI sucks, and body blocking sucks, but objectively good).

Shattering/poisonous concoction - free 6l and level 20 gem is huge. Only required unique is widowhail, which is 4 chance on average.

ice strike monk - scales extremely well through the game, freeze is very strong defensively in hc.

spark - obvious, not the strongest defensively until you chance an everlasting gaze, but it's a t4 so 6-8 chance roughly.

If you're actually planning on playing a long time, builds that benefit a lot from ingenuity/howa are quite good. Both are deterministic to acquire compared to other chase uniques.

Don't play too fast, if you're playing melee, ice strike monk is the only reasonable thing on a fresh start.

Personally, I'd recommend a class with easy access to either energy shield or MoM. Those are the only consistent ways to get a large hit pool early on for HC. Pure life builds do not have a good enough max hit to feel safe IMO.

Sockets and runes are your friends as you go through the campaign. Extra damage on your weapon and boosting resists on armor is worth it.

I've embarked on this same challenge and been having a BLAST. Currently have 4/6 classes into maps with the goal of 6/6 before a season reset. By biggest find has been that most SC builds also work for HC, but prioritize life on gear especially on acts 1-3. Resists are nice, but life and ES is mostly all you need as long as you swap charms around for bosses. I've found not getting 1 shot by boss mechanics in those 3 acts and using pots as needed instead of from panic has made runs very fun. Some bosses are Definitely worth coming back to after getting a few bosses ahead (looking at you Blackjaw/Monkey)

If U start a monk go with frost staff early game 3-14 until U get ice strike. Get ice ring or whatever it's called with unleash and frost bomb with fast forward. Ice shards with cast speed and the support gem which lowers crits but gets cast speed. Ice shards can shotgun. So cast in melee for nice DMG. Was super save for my HC ssf
