Wanted to share my take on LS raider. Feedback is welcome, I'm always looking to push this further.

See PoB notes for config explanations, min budget is probably 40ex if you want to do similar content (see bottom of post if you want budget gearing options).

This is my first time making an LS character and I was initially copying KobeblackMamba's berserker build as much as I could but using a raider (I started helix deadeye and hate leveling). After pushing as far as I could down that path I scoured poe.ninja for more ideas and iterated through changes in deli+beyond maps to lvl 100, ending up with what you see here.

Some features of this variant:

• Uses Interrogation - most raiders don't, no clue why - the math is there
• 40m+ full dps with optimal-yet-common conditions (i.e. not setting max elusive % or min point blank distance, since they're not common)
• Ignores all map mods except no regen + no leech together, which is rare (and counterable by 1 mana gain on hit from tree/jewel/claw/ring)
• Varied defensive layers with over 200k ehp before MS (not hyper-invested into one): 50/50 block, 20k armour, 10k evasion, chaos res capped, suppression capped, fortify, stun/ailment/curse immune, sap, endurance charges, elusive, blind, MS/VMS, etc...
• Ample recovery: Life gain on hit from claw, life leech, and life recovery on block (some passive regen for looting on burning ground would still be nice)

It can do w30 simulacrum easily as well as all invitations (w30 Kosis takes 15 seconds to kill at most depending on mods).

I died twice leveling from 99 to 100 in deli beyond strand: once was because I rolled a map with no leech + no regen (which let me figure out that I'm vulnerable to that combo), and once to a map with -13 max res and burning ground combined with some rippy eldritch altar mods.

This build's biggest weakness is degen but other than the burning ground and -res combo mentioned above I don't really ever feel it as long as I'm hitting things.

I used 1 inspired learning in the video to demonstrate how well the build scales with that type of mechanic in deli+beyond maps, but if you hate inspired/HH it only loses about 15% speed without it and is still plenty tanky. I run 1 inspired learning despite hating HH because it seems dumb not to, given how cheap and effective they are.

For those interested in building this with less investment, here are some gear downgrades from what I use prioritized in order of cost efficiency (copied from the PoB notes):

1. Darkray vectors (save 30ex) - lose some stats and movespeed while looting but same DPS assuming you get onslaught elsewhere. Make sure to get cold damage or lightning damage lab enchants, they make a big difference.
2. Eldritch Gloves - (save 10-15ex) - get eldritch rare gloves with +2 strike +1 pierce implicit, lose only about 7% dps from no max frenzy but also gain 2 affixes to play with
3. Belt (save 10-15ex) - don't need flask charge on crit, it's just QoL. Also don't need % life but it's very nice
4. Claw (save 10-15ex) - dont need hits cant be evaded if you allocate gear/skills to get accuracy, but it takes away flexibility on tree and gear. If you need to raise precision to lvl 20 take the precision reservation mastery and drop skitterbots. Aim for 7+crit, 2+atk speed, as much ele DPS as you can get, and preferably with a high cold damage roll.
5. Shield (save 15-20ex) - dont need life gain on block, just need 30 reservation efficiency and enough block % to cap block with versatile combatant.
6. Watcher's eye (save 5-10 ex) - only need Attack damage while affected by precision. If you don't get clarity, gem setup should change to one that costs 1-2 mana per lightning strike or you'll need about 30 unreserved mana to feel comfortable. Can use combination of divergent inspiration, replica conq efficiency, % cost reduction on jewels and ring enchant + catalysts. Can also change the skill links to have a lower mana %, such as changing multistrike to added lightning damage
7. Inspired learning without CB immun (Save 14 ex) - CB immunity isn't really needed if you can use life flask and keep yourself in situations where you are hitting stuff.

Note that the megalomaniac is not necessary if you can cap ailment avoidance on gear, but I can't be bothered to do all the gear changes necessary to get the final 10% needed so I found an Elegant Form megalomaniac with 2 random useful notables.
