Somone explain to me how to correctly use lightning strike?

So i invested around 120 ex in omni lightning strike champion but i have heard that you need to position yourself correctly if you wanna maximize damage and how do you need to use vaal lightning strike when it comes to bosses? do you attach it directly to boss or you just place it on the ground near the boss?

AFAIK the goal is to hit the boss with the projectile yourself and have a ghost bro hit the boss because you aren't close enough for the melee component for extra dps. Thats what i've gleaned from snippets here or there though so if any LS spammers want to correct me go for it lol

Sorry I know this is old. But figured if since you didn't get a clear answer I would chime in, just so ya know in the future with other builds using overlaps, or in this case strike addition enemy mechanics.

Simplest way I know to explain is simple. You wanna aim for the ground in front of the boss, so your melee misses but the projectile hits. As long as your melee misses, your additional strike will target the boss. Landing 2 hits per attack.

As far as your Vaal LS, and I'm going off what I think, so if anyone disagrees you're probably right. That skill snapshots your own damage, I believe including additional strikes, so with perfect positioning you get the 2x hit per hit as well, with 2 vaal uses, that's 4x plus your own 2x, so 6 hits per attack on bosses.

To add another tip, I didn't know at first. With his Vaal skills snapshot player DPS stats, if you have any of other buffs, like blood rage/charges/onslaught/tailwind/elusive, unsure on ancestral totem if that buff snapshots, but once all buffs are active, that's the ideal time to drop your Vaal LS. And that's the DPS most POBs is calculating, the snapshot of active buffs not the double hits unless someone adjust the count of strikes, you'll see that noted in Total DPS.

Hope you see this and it helps, or helps anyone that stumbles across this.

Been playing the Poison LS build for all of 3.18, so these extra hits really ramp up the poison dmg fast. Unsure if it's better than last leagues LS Raider, better in some ways worse in others. Might lvl Occultist to see if it's better or not. POB is hard to judge with poison sometimes, poison duration makes DPS seem higher than it really is.

Im pretty sure that additionnal strikes wont trigger if there isnt additional targets. Been fixed like 4 years ago.
