I’m level 62, and I’m still using the Chain Lightning build, mostly because it’s too much of a hassle to try other things. I just think there is something not quite right with Chain Lightning, and it’s not just how the skill is balanced but how it performs up to expectations.
When I think of Chain Lightning, I envision a spell that creates a bolt of lightning, hitting a bunch of weak enemies and destroying them. That’s what it did in Diablo 2. Chain Lightning was the skill you used to clear out packs of weak enemies, and whenever you needed to kill an elite, champion, or boss, you used something like “Lightning,” which was a single-target spell that dealt bigger damage but was a lot less efficient against packs of enemies.
The design of Chain Lightning in Diablo 4 does not fulfill this fantasy at all. Firstly, you can only cast maybe three Chain Lightnings before running out of mana. Due to the speed of the bounces, the amount of damage it does per bounce, etc., you’re lucky to notice any difference in a group of enemies’ health bars whenever you cast it. This feels really bad because you expect a spell that actually costs mana to have a noticeable impact, but it doesn’t.
On the other hand, a spell like Arc Lash seems to hit for about the same amount of damage per hit, but it feels a lot better to use. Why is that? Firstly, it attacks faster. It’s easier to attack and then, if you decide to stop attacking, it’s easier to move out of the way compared to Chain Lightning. The other thing is that it has a big radius, so you can actually hit five or six enemies at the same time if they are bunched up. You don’t have to wait for the bounces or anything, and this is a major reason why Chain Lightning seems to perform so poorly. It’s being overshadowed by a free basic attack skill that attacks faster, costs no mana, and does more damage in AoE situations.
Realizing this, I basically use Arc Lash almost all the time. I may start a battle using Chain Lightning before I get closer to the enemies, but for the most part, it’s never actually efficient to use Chain Lightning in groups despite the fact that it should bounce off multiple enemies. In fact, even when I get the unlimited mana Shrine, it’s still more efficient to use Arc Lash than Chain Lightning. How does that even make sense???
So when is Chain Lightning actually good? Against single targets, which, for a Diablo 2 player, is not intuitive at all. Unlike the slow, random bounces off enemies, the bounces between you and a single target - assuming you can engineer this situation - are extremely fast. Add the skill that increases damage by 10% with every bounce between you and an enemy, as well as the Legendary Aspect that regenerates 4-6 mana per bounce off of you, and now we’re looking at a pretty effective boss clearer that rivals the Ultimate skill.
Before you jump up and down for joy, though, this game loves to spawn bone walls or new monsters near bosses all the time, so it’s actually not so common to use Chain Lightning this way. Even if one monster is spawned - regardless of how far away it is from you and the boss - the bonus damage and mana regeneration are completely lost. This, again, makes the skill feel bad.
Even if this was the intended design, I’m not sure why these values were assigned to a skill called “Chain Lightning.” If you asked me what skill I would have wanted for a single-target boss killer that was lightning-based, I would have told you “Lightning” from Diablo 2, not Chain Lightning. But beyond that, I really don’t enjoy my “boss killer” skill to be reliant on things I cannot control, like the Boss not spawning new monsters, walls, etc. that mess with its mechanics.
But even with its intended use as a single-target killer, the drawback of the bounces makes the skill feel awful to use most of the time. It’s bad against AoE packs. It’s even not worth using if 2-3 enemies are on the screen, as it simply costs too much mana and you are probably better off using Arc Lash anyway.
The worst thing about this whole situation is that I’m basically playing Diablo 4 using a Basic Attack almost the entire time, which feels like a slog and is a totally boring way to play a Sorc. If I wanted to play a melee character, I don’t think Sorc would have been anywhere near my top 3 choices in an ARPG. Waiting every 60 seconds for my Ultimate to come online to feel any sense of power is not exactly the gameplay fantasy I was looking for to all this time.
Does Chain Lightning need a rework? Is it fine? How would you make it better?
