When you first begin playing with Lightning skills in Diablo 4, it's important to understand how much these skills depend on Lucky Hit and Critical Strike Chance stats. When you start a fresh seasonal character, you usually don't have much of these stats, which means your Lightning build won’t be very strong early on.

Lightning builds generally become effective when you reach about 25% critical chance, which you can get through your gear by level 30. Until then, it's better to either use an Incinerate build for early game or stick to playing on Normal or Hard difficulty until your gear improves buy Diablo 4 Items.

Key Active Skills for Lightning Builds
Glinting Spark (level 1/5): Use this in between your Chain Lightning casts. It helps regenerate your Mana and increases your critical chance.

Destructive Chain Lightning (maxed 5/5): This is your main damage skill. With the right legendary aspects, this can keep your Mana stable while dealing heavy damage along with your other attacks.

Mystical Teleport (level 1/5): A movement skill to help you map faster and evade danger. Its Mystical Upgrade helps maintain Crackling Energy stacks, but later, if you have other ways to keep these stacks, you might swap to the Shimmering upgrade.

Shimmering Ice Armor (level 1/5): This skill gives you a barrier and regenerates Mana, improving your survivability.

Invoked Lightning Spear (maxed 5/5): This skill is your secondary source of damage and generates a lot of Crackling Energy with the right passives and aspects. Use it whenever it’s ready.

Supreme Unstable Currents (maxed 5/5): This skill fills the screen with Shock effects and is very useful against bosses or large elite monster groups.

Early Game Tips
Spark might seem weak at first, but it’s actually very useful early on. If you're starting with this build, don't be afraid to rely on Spark more than Chain Lightning initially. Once Chain Lightning becomes powerful, you’ll mainly use Spark to regenerate Mana and keep your critical chance buff. Spark also plays an important role with Chaos Power later on.

Overall, focus on building up your crit chance and gear by level 30, and use these skills strategically to balance your Mana and deal steady damage Diablo 4 gold.
