Can someone explain what the benefit is of spellslinger? Been using it now for a couple days but not sure how to best utilize

I don’t know if it’s well known or not but you have to “glitch” it. If you’re on keyboard and mouse, set the spell in spell slinger to any number on your numpad. For example 1. Then as you get into EVERY instance you get the charges ramped up then hold (in this example) 1 then turn num lock off and let go of 1. Then proceed. It will cast automatically at that point. Hope this helps and I don’t ruin this “glitch” lol

I play on controller on pc, I set up the stream controller settings so spellslinger is a toggle. I turn it on when I jump into a map and then whenever it has energy the socketed spell just goes off automatically.

I could be wrong but, the spellslinger version basically let's you cast multiple versions of a spell at once and it bypasses the casting time- can't really speak for orb of storms specifically

Two things:

Yes, if you use a spell without a limit (like comet), it will be cast multiple times if you have enough energy stored.

Secondly, I believe it is instant, which means you dont have to actually spend time casting the spell.

(Note that I have only tried elemental invocation, but I assume spellslinger functions pretty similarly. Someone correct me if anything I said here is wrong.)

You can put more than one spell into spellslinger. I could be wrong but doesn’t orb of storms need to timeout to get the infusion? Also if you can only have 3 infusions casting 6 orbs seems wasteful? Idk what your passive tree looks like, but there’s a notable top left by the minion spirit reservation that switches remnant types. I use living bomb with overabundance to give me lightning infusions for arc and ember fusillade

Usually just hold down SS while running a map, It'll just pop off whenever you get enough charge bypassing cooldowns

I noticed some Path of Exile acronyms in this post:

• Titan - Titan, a Warrior Ascendancy class (Wiki)

I use two spellslingers because otherwise I just wouldn't have enough skill slots.

In your case, it’s not better than just casting orb of storms for the reason you think. Do you have a skill that debuffs individual enemies or creates some kind of stackable buff for your main skill’s damage? That’s what spellslinger is meant for. You could also run comet or other high damage skill and use it as burst damage on a big mob
